All-Purpose Flour

Lighter and grittier; use 3/4 cup AP flour per cup rice flour, loses gluten-free benefit

rice flour substitute
in pie crust.
A good Pie Crust depends on Rice Flour for structure and flakiness when baked. The substitute must form a workable dough that bakes up crisp, not tough.

adjustment for this dish
All-Purpose Flour develops gluten when water hits it, so mix briefly and chill immediately. Use 0.875 cup APF per cup rice flour, cut in cold 40°F butter to pea-size, and hydrate with 4 tablespoons ice water per cup. Skip the vodka — gluten already creates flaky lamination. Blind bake at 400°F for 20 minutes with weights.

Cornstarch

Best as thickener sub only

adjustment for this dish
Cornstarch gives a shortbread-like, extremely tender crust with no flaky layers. Use 0.5 cup per cup rice flour paired with another flour for structure. Cut in butter as usual but hydrate with just 3 tablespoons ice water per cup. Dock well and chill the shaped crust a full 2 hours before blind baking.
03
Oat Flour
10.0best for pie crust1 cup : 1 cup
Not GF; adds slight oat flavor
10.0
adjustment for this dish
Oat Flour's beta-glucans mimic gluten's hydration hold, giving a tender crust without toughness. Swap 1:1, cut in cold butter to pea-size, and hydrate with 5 tablespoons ice water per cup. The crust rolls more easily between parchment and develops visible flour pockets during blind bake that bake out as crisp flakes.

Sorghum Flour
10.01 cup : 1 cup
Neutral GF flour swap
10.0
adjustment for this dish
Sorghum Flour has 11% protein that gives pie crust real structure and a slightly nutty flavor. Swap 1:1, cut cold butter (40°F) into pea-size pieces, and hydrate with 4 tablespoons ice water per cup. Rest dough 2 hours, roll between parchment, and crimp with wet fingers. The flaky layers are more defined than rice flour's.
05
Millet Flour
10.01 cup : 1 cup
Mild and light, gluten-free; good for flatbreads
10.0
adjustment for this dish
Millet Flour is dry and sweet, producing a crust with a sandy, cornbread-like crumb. Swap 1:1, cut in butter as usual, but hydrate with 6 tablespoons ice water per cup since millet absorbs more. Chill dough 2 hours, roll between parchment, and blind bake at 400°F. The tender crust pairs well with sweet fillings.

technique for pie crust
technique
Rice flour pie crust can't form gluten pockets, so flakiness comes entirely from lamination of fat — cut cold butter (40°F) into pea-size pieces and keep the dough under 55°F through every step. Hydrate with ice water plus 1 tablespoon vodka per cup of rice flour; the alcohol evaporates and creates steam pockets without toughening the dough.
Rest the shaped dough 2 hours in the fridge, then roll between two sheets of parchment — rice flour dough tears without the support. Dock the bottom every inch before blind baking at 400°F with pie weights for 18 minutes, then 8 more minutes bare to set the crust golden.
Crimp with wet fingers so the edges seal rather than shatter. Unlike rice flour in bread where hydration is everything, rice flour in pie crust punishes extra water — more than 5 tablespoons per cup turns the crust tough instead of tender.
Flour pockets in the dough bake out as crisp flakes; visible butter streaks in unbaked dough predict flaky layers.
pitfalls to avoid
watch out
Don't let butter warm past 50°F — rice flour pie dough lacks gluten to carry soft fat, and above that the pea-size pieces disappear into the crust and wipe out flakiness.
watch out
Avoid more than 5 tablespoons water per cup flour — extra hydration turns rice flour dough tough rather than tender and blocks the lamination of flour pockets.
watch out
Don't roll on bare counter — parchment sheets support the fragile dough; bare counters demand so much rice flour dusting that the crimp edges dry out and shatter.
watch out
Skip chilling the shaped crust before blind bake and the sides slump — a 2-hour fridge rest keeps crust walls vertical when weights go in.
watch out
Don't forget to dock — undocked rice flour bottoms bubble into bumps that crack the crust during the second 8-minute bare bake.
