When making homemade potato salad, Ina Garten reserves the water left over from boiled potatoes, which results in a creamier salad dressing that perfectly complements the potatoes.

Garten shares this tip in her 2022 cookbook "Go-To Dinners," which she learned from the legendary Julia Child. It's similar to saving some starchy water after boiling pasta.

For the best starchy water, look for a classic Idaho or Russet potato to use. In Garten's cookbook recipe, she drizzles the potatoes with vinegar and starchy water.
