I find that 5 medium sized potatoes is good for 3 people. So for 9 it would be 15 potatoes. If you want extra do 20.
To make 700 grams of mashed potatoes, you typically need about 1 kilogram (1000 grams) of raw potatoes, as they lose weight during cooking due to water loss. The exact amount may vary slightly depending on the type of potato and how creamy you want your mash. Generally, plan on using about 1.4 to 1.5 times the weight of the desired mashed potatoes in raw potatoes.
You will need about 1 pound of potatoes per every 3 people.
About 80 pounds
You need one and 1/4 potato per person, so: - serving 4 people,= 5 potatoes - serving 10 people,=12 - 13 potatoes.
Planting potato seeds will sprout potatoes. However, in order to get edible potatoes, you will need to let the potato grow, then once you have a grown potato, you will have to cut off part of the potato and replant it.
To be safe, do your figuring in doubles, but "fudge" a little, so it's more like 1 & 1/2 to 2 per person. For baked potatoes, at least 1 per person, so make 2 per person, total 12 potatoes. You should always 1 and 1/2 or double mashed potato recipes when you aren't sure how much each person eats generally. So 12 potatoes would be 24 for mashed. In casseroles, you'd use about half to three-fourths, because the casserole has other ingredients. If sliced and browned with onion rings, at least double.The good thing about potato dishes is most people eat it and eat more than they think they will, and with potatoes you can always use the leftovers, such as mashed potatoes for fried potato cakes.
