Q&A for How to Double a Recipe

If you double the time, it will most likely burn. A suggestion is to cook for the time the recipe suggests, then check it, and if it doesn't look done, cook it for another 5 minutes or so until fully cooked.

Interestingly, bananas contain a large amount of potassium, which has been know to act as a cation in chemistry. Its ion would give off electrons. Thus when you add baking soda and powder, it actually works to minimize the ionization, which leads to a slightly acidic taste. Hydrogen will bond with potassium after losing two electrons and will result in a slightly acidic molecule. So when you increase the number for ions available, you must also increase the differential changes in the balancing elements.

The formula for the area of a cylinder (which is the volume of the cake) is (r^2)πh. 9^2 * π = 254.469. then you double this and reverse this equation. (r^2)π = 508.938, then r = 12.728, so use a baking pan with 12.5" diameter, and add 5 - 10 minutes to the cooking time.

You should multiply your spices and seasonings by 1.5 for the additional batch of beans.

Yes, but only if you are using twice the pasta. Any less pasta and it will be overpowering.
