• Yields about 10–11 small tarts (3–4 inch), depending on crust thickness and mold size. Roll to about 1⁄8 inch (3 mm).
• Italian meringue is cooked by the hot syrup, so it's safe to eat untorched. Add it close to serving for the best look.
• Make-ahead: baked shells (room temp, 1 day) and curd (fridge, up to 3 days) can be prepped ahead; assemble and add meringue the day you serve.
