Custard cream and Soy milk...

...as far as I know, you shouldn't mess them up together.
I tried twice to prepare custard cream out of soy milk, and the result wasn't great.
Suppo said it was good and licked through the pan, but I SUPPOse he's been very gluttonous this time.
If anyone succeeds in preparing a good custard cream with soy milk, please tell me!
I'll try rice milk next time, I bet it's better.
