Cinnamon Toast Crumb Crust

Preheat the oven to 325°. In a saucepan, melt the butter. Cook over moderate heat, stirring, until the butter is golden brown, about 8 minutes; strain into a glass measuring cup. Reserve the browned butter solids for the Brown Butter Custard Pie.

Pour half of the melted butter into a bowl. Add the sugar, salt, cinnamon and bread, and toss. Spread the bread on a baking sheet and bake for 35 minutes, stirring once or twice, until golden. Let cool.

Rewarm the remaining butter; pour into a food processor. Add the croutons and pulse to fine crumbs; spoon the crumbs into a 10-inch pie plate. Refrigerate for 5 minutes. Press the crumbs over the bottom and sides of the pie plate; refrigerate the crust until chilled, 15 minutes.
