Potato Flour

As thickener only; use half

cornstarch substitute
for drink.
Drinks built on cornstarch — bubble tea syrups, Mexican atole, hand-shaken thickened cocktails — demand solubility without clumping and clean suspension of particulates for 90-120 seconds in a highball glass. Cornstarch requires cold pre-hydration before boiling, then cooling to 10°C for serving. Substitutes here are ranked by dispersibility at 4°C, sweetness-masking behavior when the sugar-to-liquid ratio exceeds 15%, and how they affect mouthfeel viscosity between 50 and 150 cP.

adjustment for drink
Use half the volume. Potato flour dispersed in cold liquid at 4°C hydrates within 5 minutes without clumping, unlike cornstarch which needs slurry pre-mixing. Mouthfeel measures 100-140 cP at 1 tsp per cup — ideal for bubble tea syrups and hand-shaken thickened mocktails.
02
Arrowroot
6.71 tbsp : 1 tbsp
Use 1:1; arrowroot gives glossy finish like cornstarch, breaks down with prolonged heat
6.7
adjustment for drink
Use 1:1. For hot atole-style drinks arrowroot gelatinizes at 65-70°C and serves at 60°C without clouding. Clarity holds through 4-hour hold in a service carafe, where cornstarch turns cloudy within 90 minutes. Mouthfeel lands around 80-100 cP for a silky, not gluey, sip.
03
Tapioca
6.72 tbsp : 1 tbsp
Use 2 tbsp tapioca per 1 tbsp cornstarch; gives glossy thickening for pie fillings and fruit sauces
6.7
adjustment for drink
Use 2 tbsp per 1 tbsp cornstarch. Tapioca adds glossy, slightly stringy mouthfeel suited to bubble tea bases and Filipino-style tapioca drinks. Dispersibility at 4°C takes a 60-second whisk, roughly 2x cornstarch. Viscosity lands at 130-160 cP per tsp — slightly heavier than cornstarch's 100-130 cP.

Chia Seeds
3.31 tbsp : 1 tbsp
Ground chia thickens puddings and jams; forms gel when mixed with liquid, slightly seedy texture
3.3
adjustment for this dish
Use 1 tbsp ground chia per 1 tbsp cornstarch. Chia thickens cold drinks via mucilage gel at 20°C within 10-15 minutes — no heat needed. Adds a faint nutty top-note and roughly 2g fat per tbsp, which bumps mouthfeel past 150 cP. Suspends well for 3-5 minutes before settling.
