No, baking SODA, aka sodium bicarbonate, http://en.wikipedia....ium_bicarbonate does not contain corn, you are confusing it with baking POWDER, a mixture of baking soda, an "acid salt," and a starch, which might contain corn, or potato starch. http://en.wikipedia....i/Baking_powder
Baking soda is used with an acid you add to a recipe, typically pure apple cider vinegar, lemon juice, or yogurt, to make it fizz. The only time I've had a baking soda reaction was when I used a brand packaged by a facility that also processed oats. I switched to the cheaper, regular Arm&Hammer type and was fine.
You can make your own "baking powder" by adding a pinch of cream of tartar (potassium bitartrate http://cookingwiki.o...Cream_of_Tartar ) to your recipe along with the baking soda, but most of the time, cider vinegar and baking soda works just fine.
...So it shows I'm useless in a kitchen still =D
Oh, well. I'm learning.
Baking soda is called Natron in Danish.
I tried making a wonder-bun and it went fairly well.
I was nice and mushy but it needed more sugar and chocolate though.
Some banana would make it better I reckon.
I used rice flour and buckwheat flour.
I honestly thought it would turn out like concrete...
I'll tried and make some rice bread using yest next probably.
This is going much better than I expeted.
Thank you all.
