Tips for Substituting King Arthur Gluten-Free Flour

Here are some tips for substituting King Arthur gluten-free flour for regular flour:

Adjust leavening

Gluten-free flours produce less structure than regular wheat flours, so you typically need more leavening when using gluten-free flour blends. Increase baking powder or baking soda by 1.5 times the amount listed. For example, if a recipe calls for 1 teaspoon of baking powder, use 1 1⁄2 teaspoons.

You may also need to add an extra egg to baked goods to help with rising and structure.

Increase moisture

Gluten-free flours tend to absorb more moisture than regular flour. Increase the amount of liquid ingredients like milk or water by 25%. If the batter or dough seems dry, add more liquid as needed.

Adjust binders

Xanthan gum and guar gum help bind and add moisture to gluten-free baked goods. King Arthur flour already contains xanthan gum. But you can add 1/4 to 1/2 teaspoon of additional xanthan or guar gum per cup of flour to help improve the texture if needed.

Rest batters and doughs

Let gluten-free batters and doughs rest for 10-20 minutes after mixing. This allows the flour to fully hydrate and helps develop structure before baking.

Expect a different texture

Baked goods made with King Arthur gluten-free flour will be tender with a slightly gummy or moist texture compared to regular wheat flour. Look for recipes specifically formulated for gluten-free flours to achieve the best results.

Store properly

Like regular flour, store King Arthur gluten-free flour in an airtight container in a cool, dry place. Use within 6-8 months for the best freshness. Refrigeration can help extend the shelf life.

Troubleshooting Guide

When substituting King Arthur gluten-free flour in recipes, you may encounter some issues. Here are some common troubleshooting tips:

Problem: Baked goods don’t rise well

  • Solution: Use an extra egg for more lift and structure. Increase leavening agents like baking powder. Let batters and doughs rest before baking.

Problem: Baked goods have a dense, gummy texture

  • Solution: Add a bit more King Arthur flour to absorb moisture. Use loaf pans or cake pans with higher sides to allow more rising room. Avoid overmixing batters and doughs.

Problem: Cookies spread too much

  • Solution: Chill cookie dough before baking to prevent spreading. Use parchment paper or silicone baking mats rather than greased baking sheets.

Problem: Pizza or pie dough won’t stretch properly

  • Solution: Add a bit more flour or water to adjust the dough consistency. Allow dough to rest for 30 minutes before shaping to relax the gluten. Do not overknead the dough.

Adjusting recipes may take some trial and error when using gluten-free flours. Start by following the package instructions, then tweak according to the results you get. Checking customer reviews can provide extra troubleshooting tips.
