“Abraham hastened into the tent to Sarah, and said, ‘Make … cakes.’ Abraham ran to the herd, and took a calf, tender and good, and gave it to the servant, who hastened to prepare it.Then he took curds and milk and the calf that he had prepared, and set it before them; and he stood by them under the tree while they ate.” So cheeseburgers, basically. Delicious, but definitely not kosher.
