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.
Flour that does not have a leavening agent is called plain or all-purpose flour. It is appropriate for most bread and pizza bases. Some biscuits are also prepared using this type of flour. Bread flour is high in gluten protein, with 12.5-14% protein compared to 10-12% protein in all-purpose flour. The increased protein binds to the flour to entrap carbon dioxide released by the yeast fermentation process, resulting in a stronger rise.
