Best Matches

1:1 All-purpose flour + cornstarch (batter blend) Best overall crispness; cornstarch boosts shatter and lightness
1:1 Rice flour (white) + cornstarch (thin batter blend) Closest lace + crunch; rice flour browns fast so keep batter cold

Good Alternatives

1:1 Cake flour (or pastry flour) Fine crumb and lighter coating; works best for shrimp and delicate vegetables
1:1 Potato starch (or arrowroot) + all-purpose flour Extra crisp and dry coating; starch helps prevent dense batter

Emergency Swaps

¾:1 Self-rising flour (with baking powder adjusted down) Can fry up crisp but may taste bready; best when you need a quick stand-in

Choose the substitute that matches your goal: maximum crunch (starch blends) or lighter coating (cake/pastry flour).
Mix flour with cornstarch/potato starch/rice flour in the listed ratio (use the blend as your “tempura flour” for the recipe).
Use cold water (and keep batter chilled); for best tempura-style results, mix just until combined—small lumps are fine.
Fry immediately after battering; if it sits, the coating can hydrate and lose crispness.
After frying, rest on a rack; avoid stacking so the crust stays shattery.

For substitutes, the key is starch + minimal gluten development: cold mixing and quick frying matter as much as the flour choice.
If your substitute blend seems too thick, thin slightly with cold water right before frying.
