How Many Potatoes for Mash Formula
The formula for calculating how many potatoes you need for mash can be expressed as:
Raw Potatoes (in pounds) = (Number of People × Serving Size in Cups) ÷ 2
This formula is based on the rule that 1 pound of raw potatoes yields approximately 2 cups of mashed potatoes.
Examples
- For 6 people with a 3/4 cup serving size:
- Raw Potatoes = (6 × 0.75) ÷ 2 = 2.25 pounds
- For 12 people with a 1/2 cup serving size:
- Raw Potatoes = (12 × 0.5) ÷ 2 = 3 pounds
- For 20 people with a 1 cup serving size:
- Raw Potatoes = (20 × 1) ÷ 2 = 10 pounds
