Mayonnaise, as defined by the U.S. Food and Drug Administration's Standard of Identity, must contain at least 65% oil by weight, vinegar, and egg or egg yolks. It may contain spices and natural seasonings except turmeric and saffron, as yellow color might suggest added egg yolk. No emulsifying agents other than eggs are allowed, so real mayonnaise does not contain any starches or gums.

My chocolate cake collapses when baked at high altitudes. How should I modify the recipe?

The higher the altitude, the lower the air pressure. Increase your oven temperature to 375F, start checking doneness up to 8 minutes earlier, decrease sugar by 1 tablespoon plus 1 teaspoon (it's easiest to measure out the full 1 cups and then remove the excess), increase flour by 2 tablespoons, or increase Duke's by about 3 tablespoons. It may take a couple tries to get the recipe right at your new altitude, so try to make only one change to the recipe each time you bake and keep track of which changes worked and which ones didn't.
