Does anyone know why my almond flour turned green when I baked it?
It's a brand new bag. . . I know Sunflower seed flour turns green when baked, but I didn't hear that about almond flour?!?

Anyone know why?

I looked up how to tell if Almond flour is rancid and did not say anything about it baking green! YUCK.

If its not rancid.. (it doen't taste rancid) Maybe it's cooking it on metal cookie sheet. When I use it on a glass dish or parchment paper it didn't turn green?

I read somewhere that maybe it's the acid in lemon (it does that to garlic)
and I used lemon...
