Flatbread dough turned red Today I made some flatbread and while cooking them I noticed a reddish coloring of the dough. I didn't add anything red in particular, so I am very surprised they turned out this way. Why did that happen?
I mixed whole spelt flour and regular wheat flour, yogurt, 2 tablespoons baking soda, some olive oil, flax seeds and sesame seeds, salt, garam masala and turmeric. First I kneaded it with a mixer, the by hand, I left it to rest for 15 minutes, maybe bit more. I rolled it quite thinly with a rolling pin. I fried it on a non-stick pan.
I am actually not sure if this was safe to eat, maybe something reacted in an unexpected way?!
As Joe mentioned, there was something acting as a litmus paper!

Turmeric placed in an alkaline solution will turn bright red!

Most probably there wasn't enough yogurt or it didn't react with baking soda and left the dough alkaline.
