Potato Starch Measuring FAQs
Is potato starch the same thing as potato flour? ▾
No, potato starch is pure washed starch (152g/cup), while potato flour is ground dehydrated whole cooked potato (180g/cup).
Can potato starch be boiled vigorously? ▾
No, boiling potato starch for too long breaks down the large starch molecules, causing liquids to thin out again.
