Directions

tart crust
Step 1
Lightly grease a tart pan with removable bottom plate.
Step 2
Whisk together the flour blend, sugar, cornstarch, psyllium husk powder, and salt.
Step 3
Cut the cold butter into cubes, and work the cubes into the flour blend with a pastry cutter. Flour mix should be crumbly & resemble small pea-size chunks.
Step 4
Whisk the egg and lemon juice or vinegar together until frothy. Mix into dry ingredients. Blend until dough ball forms. Add a tablespoon or two of cold water if needed to form ball.
Step 5
Shape into ball, cover with plastic wrap, and refrigerate for at least 1 hour. Allow the dough to rest at room temperature 15 minutes before rolling.
Step 6
Place dough into tart pan and mold crust evenly on the bottom and sides.
