How much yeast for 4 cups of flour to make bread?

Here's why:

* Yeast Ratio: A general rule of thumb is 1/2 to 3/4 teaspoon of active dry yeast per cup of flour.

* Flour Amount: You have 4 cups of flour.

* Calculation: (1/2 - 3/4) teaspoon/cup * 4 cups = 2 - 3 teaspoons.

However, the exact amount of yeast will depend on factors like:

* Yeast Strength: Some yeast brands are more active than others.

* Recipe Type: Bread recipes vary. Some recipes call for more yeast for a faster rise.

* Desired Flavor: More yeast will result in a slightly tangier flavor.

Here's a more precise guide:

* For a mild, subtle flavor: Use 2 1/4 teaspoons of yeast.

* For a tangier, sourdough-like flavor: Use 3 teaspoons of yeast.

Always refer to your chosen bread recipe for specific instructions on yeast quantity.
