I have been asked how to make yogurt without using any commercial products that can be purchased. In other words, how to make yogurt from scratch.
Searching my library, I've found no help. All recipes include some reference to using "2 TBLS yogurt" or something very similar.
Certainly bread starter can be made from scratch using flour & water without buying additional ingredients. How about yogurt? Does anyone know how to do this using milk, heat and something other than "store-bought" ingredients?
