High-starch potatoes, such as russets (baking potatoes), have densely packed starch cells that swell and separate from one another when cooked, resulting in a dry, fluffy texture. High-starch potatoes also make creamy mashed potatoes and french fries with a flaky interior.
What happens to potato starch when cooked?
Simply put, the level of resistant starch in a cooked and cooled potato increases dramatically. This action improves the nutritional quality of the potato because it increases the dietary fibre load in the colon, and contains the type of resistant starch which is prebiotic.
What are high-starch potatoes good for?
Russet, Idaho and Yukon gold potatoes are starchy and great for baking, mashing and deep-frying. Their high-starch content produces an even colour when frying and their starch granules swell as they boil for the fluffiest mashed potatoes every time.
Does cooking potatoes remove starch?
Blanching potatoes in hot water helps to remove even more starch. They only need to be cooked for a few minutes until tender. The tiny starch granules absorb the hot water and swell and burst, transferring the starch from the potato to the boiling water.
What happens to potato starch when heated?
When starch is heated beyond the gelatinization temperature, granules swell up to many times their original size, collapse and release amylose in the continuous medium.
