I've added ingredients to a baking stone, and when using lore, I get:
[12:18:53] You think this may well work.
[12:18:53] Current difficulty:20.
but when trying to bake it, it never finish (gave up after about 15 min of baking time, with all ingredients boiling or glowing from heat ).
I have tested in an oven, forge and campfire, with same results.
The issue have also been reproduced by the player Iluminaty.
EDIT: Forgot about that action, it solved the issue. Thanks.
