Proofer Mode FAQs

The Proofer is calibrated to keep the contents of a jar or bowl at the designated temperature setting, not the air inside. Measuring the air temperature in the proofer with a thermometer will not indicate the temperature of food in a container.

The Proofer is calibrated to keep its contents near the temperature setting, not the air inside. This is because the Proofer heats mainly by radiative heating directly from the aluminum heating plate in the base to the food containers. The air temperature inside the Proofer will become warm, but will not be the same as the temperature of food inside containers. In Proofer mode, items should always be placed on a rack.

There are two important factors that affect the temperature of food in the Proofer:

  • Covering a container will raise the temperature of the food inside the container
  • Adding water to the tray to create humidity will raise the temperature of food in the container.

The Proofer has been calibrated in two ways:

Humid (with water tray): 21-35 °C. Use open containers. Bread dough and preferment in open bowls, loaf, or sheet pans.

Dry (no water tray): 21 – 49 °C. Use closed containers. Commonly used for culturing yogurt. If the Proofer is used in dry mode at 21-35 °C food temperatures may be several degrees below the setpoint.

Yes, the Proofer has been tested and approved for unattended operation and may be run continuously. It uses very little electricity, only about 0.03 kwh per hour when set at 75F/24C.

Inside (open):  37.5 cm x 32 cm x 20 cm high
Outside (open):  46 cm x 37 cm x 27 cm high
Outside (closed): 46 cm x 37 cm x 8 cm high
Weight: 3.5 kg

If your Proofer is set to a cooler temp (24º C), it may not feel very warm to the touch even when it is working properly. To speed rising, set it to 29-32º C. If you have been rising bread in an oven or other area that is quite warm, you may need to set the Proofer temperature higher to obtain similar results. However, the best flavors in bread are usually obtained when the dough is given enough time to rise slowly.

The Proofer has been calibrated for a room temperature of 18-21º C. The Proofer is only designed to warm its contents, not cool. If the room temperature is above the set point, the Proofer cannot be cooler. If the ambient is very cold – lower than 13C, the temperature setting may need to be adjusted a few degrees higher to achieve the desired result.

Yes, there is a thermostat located in the base of the Proofer. The heating element cycles on and off according to the temperature of the aluminum plate. This cycling on and off occurs within a very narrow range, making the Proofer very accurate and reliable at maintaining a steady temperature.

Instruction Manuals and Recipe Booklets may be downloaded on our Product Manual Support page.

The Proofer’s higher temperature range (35 – 49º C) has been calibrated for use with covered containers. Lids or other coverings need to be on containers to prevent evaporation, heat loss, and contamination from the environment.

For the best heat circulation and most accurate culturing temperature, avoid placing jars or containers directly in the center of the Proofer. The Proofer will fit eight one quart (1 liter) mason jars without the need to place a jar in the center.

For cultures or fermentations that require extended times (>12 hours) more stable results may be achieved in the Slow Cook mode, which may be set as low as 30ºC. Jars or other containers of food can be placed inside a larger flat bottom container (such as a stock pot or aluminum roast pan) and covered with a lid or foil and placed directly on the heating plate. Choose Slow Cook with the Mode button and set the desired temperature.

  1. Make sure the folding sides are collapsed correctly and attached to the hinge at the inside back of the base.
  2. Ensure the small plastic cross guides are visible on the top
  3. Place the wire rack with feet UP so it is secured by the cross guides.

proofer close up

Generally preheat for 10-15 minutes

In order to prevent the walls from coming apart, we recommend always leaving them attached to the base of the Proofer in the rear hinges, even during folding and set up.

Here are some pointers for putting them back together:

  1. Start with the long wall that says “Warning”. Place it in the rear hinges of the base so that the writing is facing the interior of the Proofer.
  2. Next take one of the short walls and face the raised hinges in the middle of the wall to the outside, or exterior of the Proofer (the smooth side of the hinge should face the interior). The exposed end of the metal pin at the center hinge of this wall should be facing up and the closed end should be facing down.
  3. To fit the short wall into the long wall, widen the angle formed by the two walls until they are nearly a straight line, then fit the juncture together.
  4. Once the juncture is fastened, you can put the short wall back to a right angle with the back wall and rest it on the Proofer base.
  5. Attach the second short wall in the same manner as the first.
  6. For the last long wall, face the raised middle panel to the interior of the Proofer, then fasten it to one of the short side walls (again, it will be necessary to widen the angle between walls until it is nearly flat).

Finally, to attach the last joint, it will be necessary to form a nearly straight line with the short wall that you are attaching it to, just as you did with the other three junctures. This will be a little tricky with the other three walls already attached. To do this, leave the back wall in the hinges at the back of the base, but lift up the walls at the front of the base so that you can form a nearly flat angle with the two walls that you are trying to attach.

No, operation of the Folding Proofer is silent.

Folding Proofer (FP-101): This model has no specific settings for slow cooking. However, most Proofers can still be used for slow cooking by setting the temperature to 120F / 49C and placing a covered cooking pot directly on the heating base plate. This will be equivalent to the FP-105 in Slow Cook mode with temperature the set at 195F.

Folding Proofer and Slow Cooker (FP-105): This model has two temperature modes: Proofer and Slow Cook. The digital display changes to indicate the set temperature for the selected mode. In Proofer mode, food items should always be placed on the rack. In Slow Cook mode, the cooking pot must be place directly on the heating base plate.

An approximate cross reference guide for using the original Folding Proofer as a slow cooker is provided below. To achieve the temperature in the left column, set the Proofer model FP-101 to the setting in the right column.

Desired Temp            FP-101 Use this Setting
195F / 90º C       =      120F / 49º C
185F / 85º C       =      118F / 48º C
175F / 80º C       =      114F / 46º C
165F / 75º C       =      110F / 43º C
140F / 60º C       =      102F / 39º C

When the Proofer is set up, the lid rests on the walls. It does not click into place or latch. However, there is a specific way to line up the lid so that it fits properly. The two square pegs at the rear of the lid fit into the square-shaped notches at the rear wall, then the lid hinges down onto the walls.

 

Slow Cooker Mode FAQs

Set to 90º C. See “About Slow Cooking Temperature” for more information. The Brod & Taylor Slow Cooker will hold food at a maximum temperature of 90º C. If you want to simmer or boil to reduce liquid after slow cooking, move the pot to a stove top.

Comparing temperature settings on The Folding Proofer and Slow Cooker to a traditional slow cooker requires some explanation. Most conventional slow cookers (typically with only Low and High settings) actually have no temperature control at all. They heat slowly and continuously until the maximum temperature is reached – usually boiling. This means for much of the time you are slow cooking, your food is actually below or above the actual ideal cooking temperature. With many slow cookers Low and High settings are actually identical. Certain “multi-cooker” appliances with a slow cook function do have temperature control, although performance varies greatly between brands and there is no universal standard for Low or High setting.

Our Folding Slow Cooker uses calibrated temperature control to maintain the selected temperature. You can choose the ideal cooking temperature for your recipe without worrying about over-cooking your food. Temperature settings are most accurate using a stainless steel pot with a flat bottom, but most any type of metal pot can be used.

 

Temperature settings will be most accurate using a stainless steel pot with a thick flat base. The best choice will have some type of heat conductive metal in the base such as aluminum.  It is possible to use cast iron Dutch ovens, either bare or porcelain coated, but these pots may be 5-8º C below the temperature setting at the highest temperatures. To achieve the highest temperature in a cast iron Dutch oven wrap it in a single layer of aluminum foil to greatly reduce its heat loss. Porcelain enameled cast iron Dutch ovens will get as hot as stainless steel pots if they are wrapped in aluminum foil.

The photographs above are of the same pot. The one on the right was taken with an infrared camera. In this photo on the right side of the pot, where there is no aluminum foil wrap, you can see tremendous emissivity of thermal heat (thermal heat energy loss). When using a recipe where a high temperature of 90º C is indicated (as in pork recipes), wrapping an enamel-coated cast iron pot or a cast iron & glass-top pot with one layer of foil on the sides and pot lid will allow the internal temperature of the pot to rise. If the temperature is set to 90º C the Proofer & Slow Cooker will not allow the internal contents of the food to rise above 90ºC.

Foil over red potOne easy method is to place 2 pieces of foil on a flat surface with the pot in the middle and then wrap to cover the pot and lid.

Different types of food are best cooked at different temperatures. Consult our RECIPES & HOW-TO for additional guidelines. In general, inexpensive cuts of meat like pork butt or shoulder, benefit from higher temperatures to become tender and should be cooked at 90º C for an extended time. Chicken is best cooked at lower temperatures to maintain moistness. Other possibilities for lower temperatures include slow roasting black garlic at 60º C or sous-vide cooking in water.

Make sure that you have removed the rack from your Proofer. The pot must sit directly on the aluminum heating base plate. Food temperature in the pot will vary somewhat depending on the type of pot. Temperature settings are most accurate using a stainless steel pot with a thick base and flat bottom. 

Folding Proofer (FP-201): This model has no specific settings for slow cooking. However, most Proofers can still be used for slow cooking by setting the temperature to 49º C and placing a covered cooking pot directly on the heating base plate. This will be equivalent to the FP-205 in Slow Cook mode with temperature the set at 90º C.

An approximate cross reference guide for using the original Folding Proofer as a slow cooker is provided below. To achieve the temperature in the left column, set the Proofer model FP-201 to the setting in the right column.

Desired Temp => Use this Setting on the FP-201
90º C        =      49º C
85º C        =      48º C
80º C        =      46º C
75º C        =      43º C
60º C        =       39º C

Slow cooking should always be done in a metal pot. Ceramic crocks and ramekins do not conduct heat well and will not reach the temperature set point.

There is no specific limit on how long the Folding Proofer & Slow Cooker may be run. Most slow cook recipes will take a maximum of 10-12 hours. Slow roasting black garlic will take up to four weeks at 60º C. The Folding Proofer original model FP-201 can also be operated for weeks and months at a time.

You may reduce the temperature setting to 70º C to safely hold food at a warm temperature. As an extra precaution, we suggest that you double check the temperature of the food to ensure that it is above 65º C. Always keep a tight fitting lid on your cooking pot inside the closed Folding Proofer & Slow Cooker.

The top and sides may be removed to use the Proofer & Slow Cooker as a warming tray. Do not remove the sides until they are folded towards the back of the Proofer. Then lift up and release the folded sides from the rear hinge. Also remove the rack and water tray. Removing the pot lid may allow food to cool below the Proofer set point.

Slow cooking is normally done with some liquid in the pot. However, in certain recipes, liquid comes mainly from the meat as it begins to cook. Consult the specific recipe for details.

The Folding Proofer & Slow cooker is approved for unattended use and can be used overnight. Please be sure to follow all safety instructions in the Instruction Manual whenever using this appliance, and especially when it is used unattended.

When slow cooking, food should reach 60° C in less than 2 hours. For this reason, frozen meat should never be placed directly in a pot for slow cooking. For best results and increased food safety, we recommend searing thawed meat. Not only does this improve the flavor but also pre-heats the pot you will use for slow cooking.

Do not immerse the base unit in water if the unit becomes soiled, instead use a soft cloth with a bit of water to remove the spill. As a preventative measure before using the Proofer, you can place a piece of aluminum foil on the base plate beneath the pot so that any spill is easy to collect and discard.
