Frequently Asked Questions

Can I use this roux for gluten-free recipes?

Yes, you can substitute the all-purpose flour with a gluten-free flour blend. Just make sure to check the cooking time as gluten-free flours may require adjustments in microwaving to achieve the desired color and consistency.

How do I know when the roux is done?

The roux is done when it has reached your desired color, typically a light tan to a deep brown, depending on usage. Keep microwaving in two-minute intervals and stir in between to ensure even cooking and to prevent burning.

Can I make a larger batch of roux?

Absolutely! Just ensure your bowl is large enough to accommodate the increased volume. Be mindful that larger amounts may require longer cooking times, so continue checking every couple of minutes until the desired color is achieved.
