earlier this morning my sister and me were making cupcakes for my moms birthday and i followed a recipe i found online and it says i need 1 3/4 teaspoons of baking soda but i dont know what is a good baking soda? i tried fanta but i dont think its a good baking soda because it didn't make the cupcakes rise. how can i tell baking soda apart from normal soda?? any suggestions for good baking sodas? (not fanta cause i already tried it and it didn't work)
