Charles Spurgeon 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)

At first they thought it was like wafers made with honey.

Getting more used to it, they, perhaps, described it quite as accurately, but not quite so sweetly; they said it was like fresh oil, and there is no better taste than that. Oil, by the time it comes to us, has usually a rank and rancid taste; but in the oil countries it is delicious; and he who has bread and a drop or two of oil, will find himself not ill supplied with a dinner. The taste of it was as the taste of fresh oil.
