For the topping, put 1/3 cup sugar and the juice of ½ lemon, into a saucepan, and stir until the juice is distributed and the sugar is dissolved. Add ½ teaspoon kosher salt; a pinch of ground nutmeg; and 5 large red delicious apples, peeled, cored and chopped into ¼” pieces, and turn the heat on very low. Cook until the apples are softened but not mushy. Put the topping aside and let it cool.
