How many sweet potatoes for 70 people?

I need more information to answer this question! Here's what I need to know:

* How are you serving the sweet potatoes? As a side dish, in a casserole, as a main course? This will help determine how much each person will eat.

* What size are the sweet potatoes? Are they small, medium, or large? This will help determine how many potatoes you need per serving.

* What are the other dishes being served? If there are other starchy sides, people might eat less sweet potatoes.

Here's a rough estimate, assuming you're serving them as a side dish:

* Small sweet potatoes: 1 sweet potato per person = 70 sweet potatoes

* Medium sweet potatoes: 1/2 sweet potato per person = 35 sweet potatoes

* Large sweet potatoes: 1/4 sweet potato per person = 17-18 sweet potatoes

It's best to overestimate slightly. It's always better to have leftovers than to run out!
