How much baking powder should be added to 8oz of all purpose flour make it self rising?

You'll need 1 1/2 teaspoons of baking powder to convert 8 ounces of all-purpose flour into self-rising flour.

Here's the breakdown:

* Self-rising flour typically contains 1 1/2 teaspoons of baking powder and 1/2 teaspoon of salt per cup (4.25 ounces) of flour.

* 8 ounces is roughly 1.88 cups of flour.

* To calculate the baking powder needed: (1.5 teaspoons baking powder / 1 cup flour) * 1.88 cups flour = 2.82 teaspoons of baking powder.

Rounding down to the nearest 1/2 teaspoon, you'll need 1 1/2 teaspoons of baking powder for 8 ounces of flour.

Important Note: This calculation assumes you are starting with plain all-purpose flour. If your flour already contains some baking powder, you'll need to adjust the amount accordingly.
