What is the best flour for gluten free biscuits?
Use a cup for cup gluten free all purpose flour blend that includes xanthan gum. If your blend does not include it, add xanthan gum as listed in the ingredients. Heads up: weights vary by brand, so if you weigh your flour, use the gram amount as a starting point and trust the dough cue. It should look shaggy, feel moist, and hold together when squeezed.
Can I make these without buttermilk?
Yes. Mix 1 tablespoon lemon juice or white vinegar with 1 cup milk and let it sit 5 minutes. Whole milk is best for tenderness. You can also use plain kefir.
Why are my gluten free biscuits crumbly?
Crumbly usually means the dough was too dry, over-floured during shaping, or the biscuits were overbaked. Add buttermilk 1 tablespoon at a time until the dough holds together. Also measure flour by spooning into the cup and leveling, or weigh it if you can. When you shape, use only a light dusting of flour. A little tacky is normal.
Do I need to chill the dough?
It helps a lot. A 10 minute chill firms the butter so it stays cold longer in the oven, giving you better layers and less spread. Chemical leaveners do the main rising, but cold butter helps the structure and flake.
Can I make them dairy free?
You can. Use cold vegan butter (the stick kind works better than tub spreads) and make “buttermilk” with unsweetened almond or oat milk plus lemon juice. The flavor will shift slightly, but the texture is still solid.
Can I make drop biscuits instead of cut biscuits?
Absolutely. Add an extra 2 to 4 tablespoons buttermilk for a thick, scoopable dough, then mound onto the baking sheet. They will be more rustic and a little less layered, but still very good.
Can I freeze unbaked biscuits?
Yes, and it is a lifesaver. Cut the biscuits, freeze on a parchment-lined tray until solid, then transfer to a freezer bag for up to 2 months. Bake from frozen at 425 F, adding 2 to 5 minutes as needed.
How do I avoid a metallic aftertaste?
If you are sensitive to it, use aluminum-free baking powder. Also do not overdo the baking soda. Measure carefully, and make sure you are using real buttermilk (or a good substitute) so the soda has enough acid to react.
