Can you thicken soup with baking powder if have flour?

No, you should not use baking powder to thicken soup if you have flour.

* Baking powder is a leavening agent. It's designed to create air bubbles and make baked goods rise. Adding it to soup will likely result in an unpleasant, foamy texture, not a thickening effect.

* Flour is a common and effective thickener for soup. It creates a smooth, creamy texture when properly used. To thicken soup with flour, make a slurry (a mixture of flour and cold liquid) and whisk it into the simmering soup.

Here's a better way to thicken soup with flour:

1. Make a slurry: In a small bowl, whisk together 1 tablespoon of flour with 2 tablespoons of cold water or broth.

2. Add the slurry to the soup: Slowly whisk the slurry into the simmering soup, stirring constantly.

3. Cook the soup until thickened: Allow the soup to simmer for a few minutes, stirring occasionally, until it reaches your desired consistency.

Remember to use a small amount of flour at first and add more if needed, as too much flour can make the soup thick and starchy.
