Use lemon zest in place of the orange, if you prefer. For the hamantaschen recipe, see here.
- 1 cup dates (about 8 oz.), pitted, quartered
- 1 teaspoon finely grated orange zest
- 1 teaspoon ground cinnamon
- 1 tablespoon unsalted butter
Bring dates, orange zest, cinnamon, salt, and 1 1/2 cups water to a boil in a small saucepan. Reduce heat and simmer, stirring often and mashing with a heatproof spatula, until dates are very soft and jammy, about 5 minutes. Add butter and stir until melted. Let cool.
Do ahead: Filling can be made 4 days ahead. Cover and chill.
