Preheat the oven to 375 degrees. Have ready an unbuttered 2-inch deep, 2 quart baking dish. Peel and cut into chunks or slices:
8 medium apples (about 2 1/2 pounds)
Spread them evenly in the baking dish. Then combine in a bowl:
3/4 cup of all-purpose flour
3/4 cup brown sugar
1/2 teaspoon salt
1 and 1/2 teaspoons ground cinnamon
1/4 teaspoon ground nutmeg.
Add 1/2 cup (1 stick) cold unsalted butter, cut into small pieces. One of these days, I'm going to buy a pastry blender. If you have one, now is the time to use it. Otherwise take two knives and cut the butter into the dry ingredients above, until the pieces of butter are a bit smaller than individual peas. You could also use a food processor, but personally, I don't think it's worth the clean-up involved.
Spread the topping evenly over the fruit. Bake until the topping is golden brown and the juices are bubbling - about 50 to 55 minutes. I don't have to tell you that this is even better when served with vanilla ice cream.
