Can you use flour instead of powdered sugar for macarons accidentally put in flour?

Unfortunately, no, you can't use flour instead of powdered sugar for macarons. Here's why:

* Powdered sugar is crucial for texture: Powdered sugar is finely ground and helps create the airy, chewy texture of macarons. Flour, even if finely ground, won't achieve the same result.

* Flour absorbs moisture: Flour absorbs more moisture than powdered sugar, which will make your macarons dense and chewy instead of light and crisp.

* Flour can cause gluten development: Flour contains gluten, which will make your macarons tough and rubbery.

What to do if you accidentally added flour:

* Start over: The best option is to start over with a fresh batch of macaron batter.

* Try a different recipe: If you're really determined to use the batter, you could try a recipe that calls for flour, like a cake or cookie. However, the macaron texture will be significantly different.

Remember, macarons are delicate and require precise ingredients and techniques for success. It's best to stick to the recipe and avoid substitutions unless you're an experienced baker.
