Hello,
I tried but I can't reproduce it. Maybe I clicked on the recipe that was under the apple pie recipe and thought I ate the apple pie.
I feel stupid, now
Sorry to "steal your time"... I'll be more careful another time.
I've cook an apple pie and directly ate it. Then, back to my inventory, it hadn't disappeared and was written in red because I'm not at level 14 yet. I've ate this apple pie, it really gave me 8% stamina, but after I fought one time my stamina was back to 0%.
So, maybe it's a bug?
