How many potatoes are needed to make 10 servings of mashed potatoes?

Here's why this is a good estimate:

* Potato Size Matters: Medium potatoes typically weigh about 6-8 ounces.

* Serving Size: A standard serving of mashed potatoes is usually about 1/2 cup.

* Yield: One medium potato will yield about 1 1/2 cups of mashed potatoes.

Here's how to calculate:

* 10 servings x 1/2 cup per serving = 5 cups of mashed potatoes needed

* 5 cups of mashed potatoes / 1 1/2 cups per potato = 3.33 potatoes

Therefore, 3-4 medium-sized potatoes should be sufficient for 10 servings of mashed potatoes.

Note: This is just an estimate. Factors like potato variety, desired consistency, and the amount of other ingredients (like butter, milk, etc.) can affect the final yield. It's always a good idea to adjust the amount of potatoes based on your personal preferences.
