Ultra-Tex is a brand of instant, cold-swelling modified starch that thickens liquids without any cooking. Because it is pre-gelatinized — cooked and dried at the factory — it hydrates the moment it hits a cold or hot liquid, building a smooth, neutral body with no starchy taste. It is a modernist-kitchen staple for thickening cold purées, sauces and drinks and for adjusting the consistency of a finished dish on the fly.
