Sorry....I was trying to make Chocolate neufatchel with 1 gallon of 2% store milk, adding 1/4 tsp CaCl; 1/8 tsp MA starter; 20 drops of vegetable rennet (5 drops/qt as per directions) following John's recipe on here, and set it aside to ripen overnight. When I opened the lid the next morning, it had good coagualtion with whey around the edges. However, it smelled funny: when I started draining it, it smelled like chocolate milk vomit (any mom knows that smell). The milk was fresh; it had the oldest expiration date and I had just bought it the day before. i know the milk source is good, it is my friends' dairy. (i often just buy mik from the store to help support them) I turned it into chocolate milk with my own powder mix.
I guess that there are a lot of things that can go wrong....but if the milk is ok, would temperature be the next variable?
