In their raw state, starch molecules are bundled tightly together into granules In order to activate their thickening power, these granules need to absorb water As water gets heated, these tiny granules gradually swell up like miniature water balloons until finally, at around 130°F, they burst, spreading individual starch molecules throughout the liquid and thickening it The starches continue to absorb water and swell further as the liquid is heated toward its boiling point When adding starch to a liquid, it’s essential to heat the sauce to serving temperature in order to gauge its thickening power There’s one thing to remember: if you add dry starch quickly to hot liquids, it rapidly forms into clumps The starches on the exterior of these clumps will swell and jell, preventing liquid from reaching the interior For this reason, it’s essential to add your starch in a form whereby the liquid can be absorbed evenly, either by combining it with a small amount of cold water to form a slurry or by combining it with a solid or liquid fat to form a beurre manié Some Common Culinary Starches There are a number of starches available in the supermarket Flour and cornstarch are the most common, but potato starch and arrowroot can also be found This chart shows you their thickening power, along with the best ways to incorporate them STARCH AMOUNT NEEDED TO THICKEN 1 CUP MILK TO THE CONSISTENCY OF HEAVY CREAM BEST WA INCORP ...
