Charles Ellicott Commentary Numbers 11:8

"The people went about, and gathered it, and ground it in mills, or beat it in mortars, and boiled it in pots, and made cakes of it: and the taste of it was as the taste of fresh oil." — Numbers 11:8 (ASV)

As the taste of fresh oil.— Or, of a rich cake of oil. In Exodus 16:31 the taste of the manna is said to have been like wafers made with honey. The ancients used flour cakes mixed with oil and honey.
