What dairy products (unless you are including butter; I use a lot of butter)? Except for pumpkin pie I can't think of anything in MY standard Thanksgiving dinner that includes dairy. I did a reasonable facsimile of pumpkin pie once with soy milk (blecch!) when my dairy intolerant niece was visiting. I would use another milk substitute nowadays if necessary (coconut?). I am always curious about what others cook for holiday meals, so I am asking for curiosity's sake. Oh, OK, I just thought of mashed potatoes (cauliflower, celery root, whatever) with cream, but I'd think that butter/ghee/duck fat plus some bone broth would fill the need there. Remember the ads that used to (still do?) run around Thanksgiving suggesting canned chicken broth instead of butter/milk in the mash, as the low fat solution?
