How much baking powder to make 5 teaspoons of soda?

You can't directly convert baking soda to baking powder. They are different ingredients with different chemical compositions and functions in baking.

Here's why:

* Baking soda (sodium bicarbonate) is an alkaline ingredient that reacts with acidic ingredients to produce carbon dioxide, causing baked goods to rise.

* Baking powder is a leavening agent that contains baking soda, an acid (like cream of tartar), and a drying agent (like cornstarch). It creates a more consistent rise in recipes.

You can't substitute one for the other directly.

If you need to use baking soda instead of baking powder, you'll need to adjust the recipe.

Here's a general rule of thumb:

* To replace 1 teaspoon of baking powder, use 1/4 teaspoon of baking soda and 1/2 teaspoon of cream of tartar.

However, it's best to consult a reliable baking resource or recipe to find the correct amount of baking soda to use in a specific recipe.
