Flour vs corn? Which do you prefer? Myself, I think there's nothing better than a homemade corn tortilla slathered with butter. I make both flour and corn by hand.
Depends on whether they're for snacking or for composing a dish.
Cannot choose. They are both used for different things. Flour - burritos, soft tacos, sopaipillas. Corn - tacos, tostadas, tortillas, enchiladas. It's all good.
