This tradtional pie is one of those stealth desserts that seem too simple to be true but then takes hold of your palate after the very first bite. The filling is made by cooking sugar, almonds, and milk until the mixture caramelizes and thickens, and that's it. Pure genious. Be sure to heed the recipe and partially bake the pie crust before adding the filling so it stays crisp on the bottom rather than soggy.
