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.
Not true. White whole wheat flour is making a good run at becoming part of mainstream American baking. Traditional all-purpose, or white, and whole wheat flours are milled from hard red wheat berries; both flours contain the wheat's endosperm, while whole wheat flour also contains the bran and germ. Whole wheat white flour is milled from the hard white wheat berry. It contains the entire wheat berry; the difference is in the white berry's bran, and the result is a lighter colored, sweeter tasting flour.
