Weight Watchers Gluten Free Bagels

all purpose gluten free flour (I recommend Better Batter (or my mock blend) or Better Than Cup4Cup—both recipes in the link), plus about 1 tablespoon more (9 g) for sprinkling

xanthan gum (omit if your blend already contains it)

baking powder

kosher salt

nonfat Greek-style plain yogurt, straight from the refrigerator

egg white (25 g), chilled

Egg wash (1 egg + 1 tablespoon lukewarm water, beaten) (optional)

Toppings (optional) like sesame seeds, poppy seeds or Everything But the Bagel seasoning from Trader Joe’s
