Genesis 18:6-8

6So Abraham hurried into the tent and said to Sarah, “Quick! Take three measures of fine flour, knead it, and make bread.”

7Then Abraham ran to the herd and chose a fine, tender calf, and gave it to a servant, who quickly prepared it.

8Abraham then took some curds and milk, along with the calf that had been prepared, and placed the food before them. They ate while he was standing near them under a tree.
