My sister's newborn has a dairy allergy, so she has to stay dairy-free while nursing. Good grief. My Thanksgiving menu is a butter lover's delight. I'd like to make sure she can still enjoy her favorites. Do you think I could substitute duck fat for butter in recipes like stuffing (for sauteeing the onions, etc) and what about for what usually is my herb butter that gets rubbed on the turkey? I know i can use olive oil, but i like the richness of butter flavor for my holiday cooking. Your opinions and suggestions are appreciated!
