The call
Use cornstarch
for rice starch.
Match by power. Equal-power tier (cornstarch, quick-cooking tapioca, instant tapioca, Instant ClearJel, rice starch, modified food starch) swaps 1:1. Arrowroot/kuzu ~1.5x cornstarch dose; potato ~2 tsp per 1 Tbsp cornstarch; wheat ~1.25-1.5 Tbsp per 1 Tbsp cornstarch. Slurry in cold liquid; simmer cornstarch/wheat/rice 1-2 min after thicken; pull arrowroot/kuzu/potato off heat at thicken.

Ratio
1 : 1 within an equal-power tier; otherwise dose by power
Why this works
The starches group covers two things: thickening power per gram, and how the set behaves under acid, dairy, sustained heat, and freeze-thaw. Cornstarch, quick-cooking tapioca, instant tapioca, Instant ClearJel, rice starch, and most modified food starches sit in an equal-power tier: 1 Tbsp of one is ~1 Tbsp of another in a fruit pie or thickened sauce, with King Arthur treating cornstarch, quick-cooking tapioca, and Instant ClearJel as 1:1 by weight in pie fillings. Arrowroot and kuzu give a softer, glassier gel at ~1.5x the cornstarch/tapioca dose. Potato starch is the most powerful common target (~2 tsp per 1 Tbsp cornstarch); wheat starch lands close to potato (~1.25-1.5x cornstarch). The harder constraint is fit: cornstarch, rice, and wheat starch fail in acidic fruit pies, lemon curd, vinegar pan sauces, and tomato/wine reductions because acid hydrolyzes the gel; tapioca, ClearJel, arrowroot, and kuzu are the acid-tolerant targets. Arrowroot, kuzu, and potato turn slimy or break in dairy-rich and high-protein sauces and in long simmers, where cornstarch, ClearJel, and rice starch hold. For freezer pies and make-ahead sauces, tapioca, ClearJel, arrowroot, and kuzu freeze and thaw without weeping; cornstarch- and rice-starch-thickened sauces weep and thin. Instant tapioca behaves like quick-cooking tapioca but needs 15-30 minutes resting before baking so the granules soften.
Sensory diff
- Flavor
- All of these starches are essentially neutral; the only flavor risk is undercooked cornstarch, wheat starch, or rice starch, which read raw and chalky if pulled before the gel sets.
- Texture
- Cornstarch, rice, and wheat starch set cloudy and softly opaque; tapioca, ClearJel, kuzu, and arrowroot set glossy and clear; tapioca-thickened fillings read sticky or stippled if granules are not fully softened; arrowroot- and kuzu-thickened sauces feel silkier and wobblier than cornstarch; potato starch sets shiny and slightly looser, almost custardy in roux-style sauces.

Adjustments
- ratio
- Match by power, not by spoon: 1 tbsp cornstarch = 1 tbsp quick-cooking tapioca = 1 tbsp Instant ClearJel = 1 tbsp rice starch = ~1.5 tbsp arrowroot or kuzu = ~2 tsp potato starch = ~1.25-1.5 tbsp wheat starch.
- acidity
- For acidic fillings (rhubarb, cherry, citrus, vinegar pan sauces, wine reductions, tomato gravies), avoid cornstarch, rice starch, and wheat starch; reach for tapioca, instant tapioca, Instant ClearJel, arrowroot, or kuzu instead.
- heat
- Cook cornstarch, rice starch, and wheat starch a full 1-2 minutes after they thicken to cook out raw starch and set the gel; pull arrowroot, kuzu, and potato starch off the heat the moment the liquid thickens, because extended boiling and aggressive stirring thin them.
- dairy-balance
- For cream sauces, cheese sauces, and gravies built on milk or stock with dairy, stay with cornstarch, Instant ClearJel, or rice starch; arrowroot and kuzu can read slimy in dairy, and potato starch breaks under sustained heat.
- freeze-stability
- For freezer pies and make-ahead sauces, choose tapioca, instant tapioca, Instant ClearJel, arrowroot, or kuzu; cornstarch- and rice-starch-thickened sauces tend to weep and thin after freezing and thawing.
- consistency
- Slurry every starch in cold water, juice, or stock before adding to a hot pan, and let instant tapioca-thickened fillings rest 15-30 minutes before baking so the granules soften and the filling doesn't read stippled.
Where to be careful
- Highcornstarch — Medium. High when an acid-sensitive starch (cornstarch, wheat starch, rice starch) is asked to set an acidic fruit pie, lemon curd, or vinegar/wine/tomato sauce; high when arrowroot, kuzu, or potato starch is held at a hard simmer or stirred aggressively after gelling (the gel breaks and thins); high when a cornstarch- or rice-starch-thickened sauce is frozen and thawed (it weeps); medium when wheat starch is used in a recipe that depends on a fully glossy or fully clear set.
- Higharrowroot powder — Medium. High when an acid-sensitive starch (cornstarch, wheat starch, rice starch) is asked to set an acidic fruit pie, lemon curd, or vinegar/wine/tomato sauce; high when arrowroot, kuzu, or potato starch is held at a hard simmer or stirred aggressively after gelling (the gel breaks and thins); high when a cornstarch- or rice-starch-thickened sauce is frozen and thawed (it weeps); medium when wheat starch is used in a recipe that depends on a fully glossy or fully clear set.
- Highpotato starch — Medium. High when an acid-sensitive starch (cornstarch, wheat starch, rice starch) is asked to set an acidic fruit pie, lemon curd, or vinegar/wine/tomato sauce; high when arrowroot, kuzu, or potato starch is held at a hard simmer or stirred aggressively after gelling (the gel breaks and thins); high when a cornstarch- or rice-starch-thickened sauce is frozen and thawed (it weeps); medium when wheat starch is used in a recipe that depends on a fully glossy or fully clear set.
