I have been making yogurt with the Richuang yogurt machine for a long time, and I am still very experienced in this piece. Using yogurt machine to make yogurt is mainly to choose starter, you can choose yogurt or mushroom powder. If yogurt is used as starter, the mixing ratio of yogurt and milk is 1: 10. If you choose mushroom powder to make yogurt, 1g mushroom powder can make 1L yogurt ~ ~ Just choose plain yogurt, preferably brand-name yogurt, which has high concentration and is easy to succeed; Major supermarkets also sell mushroom powder, which is similar.
