Prepare the corn for grilling. Brush the kernels with butter or olive oil and season with salt and pepper, or these gourmet options.

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.
Flour intended to be used to bake cakes and pastry is made from soft wheat. All-purpose flour is made from a blend of soft and hard wheat.
