I just roasted a five pound duck this weekend, and there was easily four cups in the pan afterwards.

Yeah, about four cups sounds right, maybe a little less. Duck fat is amazing on roasted carrots and onions.

I have about two cups in my freezer from 1 duck.

i have yet to purchase duck(s). i am trying to determine how many i need. what i am looking for is how much fat i can expect to render per pound of duck.

thank you all for your answers so far.

do you by any chance remember the size of the duck?

This is variable, but you should expect 1.5 - 2 cups per duck.

Unless I miss my guess, you're thinking about confit, so I'll just tell you my rule of thumb: the fat rendered from one duck is generally sufficient to confit two legs from a similarly sized duck.

i am actually thinking french fries but thank you for the information.

8 ducks to the gallon it is.

No, I don't. It was a Canadian duck, if that helps (it probably doesn't...). I would guess it was at least five pounds and no more than 7.

I know you're making fries (and not roast duck), but here's what my husband said when I sent him this link:
I think what I've done in the past is to get a couple of ducks, and take off the good bits -- legs and breasts. Then trim up those good bits and keep the trimmings (skin and fat). Then I trim up the carcass, again keeping the trimmings. Roast the carcass and wings. Keep the roasted bones for stock, and strain and collect the fat that comes off. Render the trimmings and add the collected fat to that collected from the bone roasting exercise.

Ducks are expensive. This is how I make the most of them.

I'm also quite fond of potatoes fried in goose fat. A ~12lb goose should give you somewhere northwards of 48 oz of rendered fat.
