Sunflower Seed Flour
Sunflower Seed Flour (also: Ground sunflower seeds | Sunflower meal). Mild, slightly nutty. May turn green with baking soda.
Naturally gluten-free. That describes the plant. On a pack, any gluten-free wording, 'naturally gluten-free' included, legally means the flour inside is within the 20 ppm limit (EU, UK, US); flour without it can pick up gluten in the mill. ⚠ COLOUR REACTION: sunflower flour + baking soda/powder = green discolouration (chlorogenic acid). Add apple cider vinegar to prevent.
