Rice Flour

Gluten-free with fine crumb; best blended with other flours for structure

cake flour substitute
for frying.
Frying batters built on cake flour crisp up because low protein keeps the coating shatter-light at 350-375°F oil, where bread-flour batters would chew. Fine starch granules absorb less oil during the 3-4 minute fry window, so finished tempura or katsu drains drier. A swap must survive sustained 350°F immersion without pulling moisture from the protein and turning the crust soggy within 60 seconds of plating.

adjustment for frying
Swap 1:1 in tempura batter. Rice flour's zero gluten gives a shatter-light crust at 350-375°F that stays crisper longer than cake flour — about 8-10 minutes after plating versus 5-7. Mix the batter with 40°F ice water and use within 90 seconds before gluten-free starches start to slack.
02
Cornstarch
6.7best for frying2 tbsp : 1 tbsp
Blend 2 tbsp cornstarch with 14 tbsp all-purpose flour to mimic 1 cup cake flour
6.7
adjustment for frying
Blend 2 tbsp cornstarch with 14 tbsp AP for fried-coating dredge. The cornstarch fraction crisps audibly at 350°F and resists oil absorption better than pure cake flour, holding crunch through 10 minutes of plating. Use straight cornstarch for the lightest crust on Korean-style double-fried chicken.
03
All-Purpose Flour
6.77/8 cup : 1 cup
Use 1 cup minus 2 tbsp AP flour per cup cake flour; sift twice for lighter texture in delicate cakes
6.7
adjustment for frying
Use 7/8 cup AP per cup of cake flour for fried dredge. Higher 10-12% protein gives a chewier crust at 350-375°F that holds sauce better but loses the lacy shatter of cake flour. Sift twice and dredge cold for thinnest coating; let rest 5 minutes pre-fry.

Bread Flour
6.77/8 cup : 1 cup
Higher gluten so use less and add 2 tbsp cornstarch per cup; crumb will be denser
6.7
adjustment for this dish
Use 7/8 cup bread flour with 2 tbsp cornstarch per cup. Bread flour's 12-14% protein produces a tougher fried crust at 375°F that resists steam softening for 12-15 minutes — useful for fried chicken under hold lights, less ideal for delicate tempura.
05
Whole Wheat Flour
6.77/8 cup : 1 cup
Nuttier flavor and denser crumb; best in muffins or quick breads, not delicate cakes
6.7
adjustment for this dish
Swap 7/8 cup per cup but expect dense, brown-flecked crust. Whole wheat browns 30 seconds faster than cake flour at 365°F because of bran sugars, so drop oil to 350°F to avoid burning. Best for hearty fried items like falafel or okra, not delicate seafood.
06
Spelt Flour
6.71 cup : 1 cup
Slightly sweet and nutty; lighter than whole wheat but denser than cake flour
6.7
adjustment for this dish
Swap 1:1 by cup. Spelt fries to a crust slightly denser than cake flour with a faint nutty edge that complements fried mushrooms or eggplant. The lower gluten strength means the coating can flake off if the food isn't dredged through egg wash first to anchor it.
07
Semolina Flour
6.71 cup : 1 cup
Finer grind works in sponge cakes; yields chewier, denser crumb than cake flour
6.7
adjustment for this dish
Swap 1:1. Semolina's coarse durum particles give an audibly crunchier crust at 365°F — useful for arancini or fried calamari rings — but the texture turns gritty on delicate fish fillets. The crust stays crisp 10-12 minutes versus cake flour's 5-7.
08
Cassava Flour
3.31 cup : 1 cup
Gluten-free 1:1 swap with neutral flavor; texture is slightly gummier
3.3
adjustment for this dish
Swap 1:1 by cup for gluten-free frying. Cassava produces a crust slightly gummier than cake flour at 350°F because its starch gels denser — counter by mixing 50/50 with cornstarch. Drain on a wire rack since the crust softens within 90 seconds on paper towels.

Oat Flour
6.71 cup : 1 cup
Mild sweetness; makes tender crumb but results are slightly more crumbly
