The corn flour I got was slightly moist, sold in a plastic bag in the refrigerated section. I believe it was intended for African dishes, not for tortilla making. It doesn't look or smell like regular masa, though the texture is similar. There is no lime in this corn flour.
It has a very sour "buttermilk" kind of smell. Has it gone bad, do you think?
Does anyone has experience with this type of corn meal? Should I just not even eat it if it smells this way, or is this normal?
Will it make something like a corn tortilla, or is the lime in masa necessary for success?
