Making Probiotic Superfoods at Home

Homemade Tempeh

Tempeh adds nutrition to salads.

Scientific research is clear: incorporating live probiotic cultures into your diet boosts the immune system and promotes digestive health. Yogurt is one of the best-known live culture foods, but there’s a world of incredible probiotic superfoods out there, each of them delicious and uniquely beneficial. Lacto-fermented pickles and sauerkraut (fermented in water, instead of pickled in vinegar) are making a comeback, with more and more people culturing them at home. Kefir and kefir water energy drinks are also easy to make, delicious and very nutritious. Homemade cheese, kimchi, tempeh, kefir, kombucha – these superfoods literally bubble over with fresh flavor and health benefits.

With a temperature range of 70F-120F and the durability to operate for as many hours or days as necessary, the Proofer provides an ideal environment for fermenting and culturing probiotic superfoods. Each food has a different optimal temperature for culturing, making the digital control of the Proofer vital for success:

  • Kombucha does best from 72-82F/22-28C.
  • Tempeh is cultured at 88F/31C.
  • Japanese Natto needs a steady 100F/38C.
  • Kefir and kefir water drinks work in a range from 70-85F/21-29C.
  • Home cheese makers need to hold milk at steady temperatures of 72-102F/22-39C during ripening.

      Anne, Thank you for your interest. Many people have asked us about making natto. We will have instructions with photographs posted on our website within the next few months. We spend quite a bit of time testing different methods and temperatures prior to posting the final instructions.

    I’ve just bought this appliance, which saved my sourdough starter as it’s too cold otherwise in my house. However I am intending to culture many different foods like water and dairy kefir, cultured dairy (raw cheese & yogurt), natto, tempeh & kombucha as well as fermented veg/ fruit. However I’ve heard that you can’t ferment different cultures together within a 5 foot distance. Is this information correct? Is there a way that I can put several different ferments together in the proofer e.g. sourdough and kefir etc. without them spoiling? Which cultures are compatible?

      This is a very interesting subject. We recommend you contact Cultures for Health for assistance determining which foods can be fermented at the same time. You are correct that some food cultures are not compatible with other foods and their cultures. Here is a link to the Cultures for Health website: We believe they are the most knowledgeable about food cultures and can assist you. They also sell our Folding Proofer & Slow Cooker so they are familiar with our product too.

    I can’t find any details or recipes on fermenting vegetables. Is there any information specific to this proofer of do I need to wing it based on general recipes.

    Thanks! Just got my Proofer yesterday for Xmas. I’ve been wanting one forever for my bread making but I’m looking forward to cheese and yogurt too.

      We have recipes for making fresh cheese and yogurt on our website. Our Custard-Style Yogurt is a customer favorite. For information, ingredients and supplies for fermenting vegetables we can refer you to Cultures for Health. Many of the jars and containers used for fermenting batches of vegetables do not fit in the Proofer and can be made without a Proofer. During the winter we do have customers use smaller containers to ferment vegetables so they will fit in the Proofer and maintain a warm enough temperature. We hope you enjoy your Proofer and take a moment to look at our website for more bread recipes. Thank you for your purchase and let us know if we can assist you in the future.
