You remark that Windcaller has been here more often than you have, and ask if he has any recommendations.

Windcaller: "It... depends. If you're hungry right now, we can harvest some hay. But... if you'd like to use some of the apples you bought, we could try something else."

Moonflower: "Oooh! What'cha got in mind?"

Windcaller: "Let's see... if we work together, apple crisp should be simple enough to make. Two of us can harvest some oats and some wheat, while the other prepares the apples for the filling. The windmill should have everything else we need."
