Modified Starch

Many of the hydrocolloid thickeners in use in today’s modernist kitchens are pre-treated starches (such as tapioca), which dissolve more readily than the original starch. Wondra brand is an example of flour that has been pre-hydrated, gelatinized, and toasted. Once made into a smooth slurry with water, its rather large particles are stirred directly into a sauce, gravy, or jus without lumping. This is a boon to those who don’t want to bother using a roux or beurre manié. Modified starches are useful because they can be used without pre-gelatinization or hydration.
