I just called Bob's Red Mill customer service (just do a G search for the company, their customer service number is under "contact us" on their site), and I was annoyed to learn that NONE OF BOB'S RED MILL BAKING SODA CONTAINS ALUMINUM. I've been paying $10-15 (with shipping) for this magical 'aluminum free' baking soda only to learn that the Bob's Red Mill 'premium baking soda' at my local grocery is the same exact thing. Call for yourself if you don't believe me. Ugh.

I have been on GF diet for a month and it's hard to find food that taste good or even close to what I used to eat. But when my husband found Bisquick Gluten Free at the store, the issue of what to eat for breakfast never came up. Actually my husband eats the GF pancakes wnow even if he doesn't need a gluten free diet. The pancakes are lighter and very tasty. Just follow the box directions.
