Here's a "simple" dessert adapted from bon appetit's comfort food issue.
1 1/4 cups all purpose flour
12 tablespoons sugar
3/4 teaspoon ground cinnamon
1/4 teaspoon salt
1/8 teaspoon ground nutmeg
125 grams (1 1/4 sticks) chilled unsalted butter, diced
1/2 cup sugar
1/4 cup (1/2 stick) unsalted butter, diced
2 tablespoons fresh lemon juice
(use water if you don't want your filling to be sour)
1/2 teaspoon salt
6 golden delicious apples, peeled, cored and sliced
Whisk first 5 ingredients in a bowl to blend. Add butter and rub in with fingertips until small moist clumps form. Cover and chill.
Preheat the oven to 375 deg F. Stir sugar and butter in large skillet over medium heat until smooth sauce forms. Add lemon juice and cook, stirring, until caramel is deep brown, about 5 minutes. (It is very important not to burn the caramel, or else it will turn bitter). Mix in salt, then apples. Toss until apples are evenly coated. Scrape apples and caramel into 13x9x2-inch glass baking dish; spread evenly. Sprinkle topping evenly over.
Bake crisp until apples are tender, sauce is bubbling thickly, and topping is golden, about 50 minutes. Let crisp cool 15 minutes before serving with a scoop of vanilla ice cream.
