A question about a recipe: Thyme and Duck Roasted Sweet Potatoes and Celery Root: Where do you buy duck fat?

Sorry I didn't see this until now! There is a duck producer at my farmers market who sells it, but it can also be purchased from a butcher, or an upscale grocer, like hardlikearmour mentioned.

If you don't live near any of those options, you can buy it from D'Artagnan: http://www.dartagnan.com/51465/731861/Duck-Fat--Demi--Glace/Duck-Fat.html.

i don't know where you live but if you go on www.chowhound.com to your local board, other chowhounds should be able to help you.

If you're into using Goose fat, which I find preferable to duck, try this place:

I can find it in the freezer section of my local, fairly upscale grocer. I can also get it at a couple of local butcher/charcuterie places.
