How many potatoes are needed to make mashed for 7 people?

It depends on how much mashed potatoes each person eats! Here's a guide:

Small appetite: 1 medium potato per person (7 potatoes total)

Average appetite: 1.5 medium potatoes per person (10.5 potatoes, round up to 11)

Large appetite: 2 medium potatoes per person (14 potatoes total)

Here are some factors to consider:

* Potato size: Medium potatoes are about 2-3 inches in diameter.

* Side dishes: Will mashed potatoes be the main dish or a side? If it's a side, you'll likely need less.

* Other factors: Consider individual appetites, if anyone has dietary restrictions, and how much you like leftovers!

Tip: It's always better to have too much than too little, as you can always use extra mashed potatoes in other recipes (like potato pancakes or soup).
