Alton Brown had this “Turketta” recipe on his new show:
What you do is create an herb-flavored butter by heating the butter with herbs. One of the people coming to our holiday is Jewish, so in an effort to stay close to halal/kosher, I was thinking of substituting duck fat instead of the butter. I would then keep any left over duck fat for other recipes.
Do you think this would work?
By the way, the rule against mixing dairy and meat is a tough one. This is why, when the saturated fat hysteria came along, the Jewish moved largely to plant oils. That likely was not a great move. They used animal fats (e.g., schmaltz, chicken fat) until then.
