Preheat the oven to 375°F. Melt 1 tablespoon of butter and spread it evenly in a 9×13-inch baking dish, sheet pan, or another pan with sides.
Place the rolls over the butter. Cut an X into the rolls about ⅔ down but not completely through the bottom of the rolls.
Zest one lemon, then juice it. You'll get about 1 teaspoon of zest and 1 tablespoon of juice. No need to be exact, just use one lemon.
Stir together the ⅓ cup butter, honey, and lemon zest. Pour evenly over the rolls.
Sprinkle the 1 tablespoon of granulated sugar over the rolls.
Now you'll add the lemon curd to the 'X's you cut in the rolls. It's easier if you use a piping bag with a large tip on it to pipe the lemon curd into the rolls.
Bake the rolls, uncovered at 375°F for 12 to 15 minutes.
Allow the rolls to cool while you're mixing the glaze. Whisk the lemon juice, powdered sugar, and 1 to 2 tablespoons of heavy cream together until smooth. Pour it over the rolls.
Serve warm. Store any leftovers in an airtight container in the refrigerator. They'll keep 3 to 4 days.
