Hi Rabbi,
Is Trader Joe Kefir OK for Pessach? The ingredients are :
pasteurized goat’s milk, tapioca starch, live and active cultures streptococcus thermophilus bifidobacterium lactis, lactobacillus acidophilus, l. casei, l.rhamnosus, l. lactis, l. bulgaricus)
Here is a link also with more details : https://www.fooducate.com/product/Trader-Joe-s-Goat-Milk-Kefir-Plain-Unsweetened/5B018DB0-A48B-0DB3-4F38-8BA77736E53F
If not is there a kefir that is kosher for Pessach?
Thank you
