I have a dairy cow, and when I leave its raw milk on the counter for a couple of days, I end up with clabber (also called clabbered milk). However, I am not willing to take the risk of consuming non-pasteurized milk products during a global health pandemic. I want to try out some recipes that use uncooked clabber. And since there are cultures that can be added to pasteurized milk to make kefir, yogurt, and cheeses, I thought surely there must be some that can be added to make clabber! Alas, I have not been able to find any information on this.
What specific bacterial, fungal, or yeast cultures can be added to pasteurized milk to create clabber?
