TSK · Exodus 29:31

Then Moses said to Aaron and his sons,“Boil the meat at the entrance of the Meeting Tent, and there you are to eat it and the bread which is in the ordination offering basket, just as I have commanded, saying,‘Aaron and his sons are to eat it,’

Also, before they burned the fat the priest’s attendant would come and say to the person who was making the sacrifice,“Give some meat for the priest to roast! He won’t accept boiled meat from you, but only raw.”
