How much egg white do you need if use 3 lb of flour?

I can't tell you how much egg white you need for 3 lbs of flour. Here's why:

* Recipe Dependent: The amount of egg white needed varies greatly depending on the specific recipe you're using. Some recipes call for a lot of egg white (like angel food cake), others use very little (like a basic bread recipe).

* Egg Size: Egg sizes vary, and this impacts how much white you get from each egg.

To figure out how much egg white you need, you'll need to:

1. Find the recipe you want to use.

2. Check the recipe for its specific egg white requirements.

Let me know if you have a recipe in mind, and I can help you calculate the amount of egg white needed!
