Soy Milk Yogurt Recipe

Soy yogurt 3 300x261This soy milk yogurt recipe makes a thick and creamy alternative to cow’s milk yogurt with the nutritional benefits of soy.

Culturing soy milk adds beneficial probiotics and also helps neutralize phytic acid, a naturally-occurring compound in soybeans that can bond with minerals, making them less bio-available. Our testers enjoyed this soy milk yogurt best slightly sweetened and with a drop or two of good lemon oil.

*Live culture yogurt can be store-bought soy yogurt with live cultures or regular dairy yogurt with live cultures. Or a direct-set vegan starter may be used according to package directions. Learn more about how to maintain a yogurt culture.

Equipment: Brød & Taylor Proofer, thermometer, glass mason jars or other heat-proof containers with a capacity of one quart / one litre or less. Everything that will touch the milk should be thoroughly clean and dry.

Note: When using the Folding Proofer to make yogurt, be certain there is no water in the water tray. The water tray is not needed for making yogurt. You can remove it from the Proofer, if you like, or leave it empty. But do not add water because it will affect temperature settings.

Step One: Heat Milk to 90 ºC and Hold for 10 Minutes. Using either a microwave or the stovetop, heat soy milk to 90 ºC. If using the stovetop, stir frequently to prevent scorching. Hold the temperature of the soy milk above 90 ºC for ten minutes. Depending on batch size, it may be necessary to use low heat (stovetop) or a short burst in the microwave to keep the soy milk hot.
Tip: Whisking the milk to cover the surface with bubbles will prevent the milk from forming a skin during heating and cooling.

While the milk is cooling, set up the Proofer with the wire rack in place and the temperature at 49 ºC.

Step Three: Add Yogurt and Flavourings. Put the yogurt with live cultures into a small bowl. Gradually stir in enough of the warm soy milk to liquefy the mixture and mix until smooth. Then pour the liquefied culture back into the large container of soy milk and stir gently to distribute. Stir in optional sugar and flavourings. Pour the soy milk mixture into jars, cover and place in the Proofer. Tip: For proper heat circulation and the most accurate culturing temperature, arrange the jars so that they are not directly over the center of the Proofer.

Set a kitchen timer for one hour, then after that hour turn the Proofer down to 30 ºC. It’s important not to let the yogurt remain at 49 ºC for more than an hour in order to avoid the whey separation and lumpy texture that come from culturing too hot.

Step Five: Check the Yogurt after Three Hours. After one hour at 49 ºC and another two hours at 30 ºC, check the yogurt by gently tilting a jar to the side to see if it has set. Most yogurts will take about 3-4 hours to set, or the yogurt can be cultured longer for a more tart flavour. When the yogurt is ready, put it into the refrigerator and allow it to chill thoroughly. Be sure to reserve enough yogurt to start your next batch.
