Wanted to flip them again and had a surprise: They are growing... When they came out of the moulds they were 23 cm in diameter, just like the moulds of course. I placed them on trays that are 25cm wide and the Brie's are just that wide, but not only that, they are blowing. Not much but definitely. And when I had an other tray on top and flipped them... well, I can call it "Brie Blowing Bubbles" but it was more like a farting Brie, however odorless.
Anybody any idea why? I used a blob of soja yogurt with Lactobacillus Bulgariensis and Streptococcus Cremoris, but they are not supposed to be gas forming, or am I completely wrong and did I do a stupid thing? They smell good and look good until now....
