1. Make a Slurry (Just Like Cornstarch)
Mix 1 to 2 tablespoons of tapioca flour with an equal amount of cold water. Stir until it’s a smooth, milky paste. Never dump the flour directly into hot liquid—you’ll get clumps, and nobody wants clumps.
2. Whisk into Hot Liquid
Pour your slurry into the simmering sauce while whisking constantly. Watch it transform before your eyes! It thickens almost immediately, so don’t walk away. Remove from heat once it reaches your desired consistency.

Pro tip: tapioca can get stringy if you overcook it. Think of it like a shy friend—once you’ve introduced it, let it rest. A quick boil is all it needs.
