Prepare the corn for grilling. Brush the kernels with butter or olive oil and season with salt and pepper, or these gourmet options. Roll each corn cob in a square of aluminum foil, twisting the ends to secure, like a candy wrapper. If you prefer, you can wait on the butter and herbs until the corn is cooked.
Baking powder is a mixture of baking soda, calcium acid phosphate, and starch. It is used as a leavening. Baking flour is ground wheat and covers all flours used for baking, including cake flour, pastry flour, all-purpose flour, and self-rising flour. So yes, there is a very big difference.
Baking powder is basically a blend of acid (most commonly calcium acid phosphate, sodium aluminum sulfate or cream of tartar) and alkali (sodium bicarbonate known commonly as baking soda). By adding water to this mixture, a chemical reaction is achieved, producing carbon dioxide which is trapped in tiny air pockets in the dough or batter.
