These elegant tarts feature a rich, silky custard infused with aromatic saffron and bright orange zest, broiled to a perfect golden-brown caramelization on top for a quick, impressive dessert. They are a Spanish-inspired delight that's surprisingly simple to prepare.
Storage: These tarts are best enjoyed fresh and warm from the broiler. They can be stored, covered, in the refrigerator for up to 1 day, but the custard may weep slightly. Reheat gently under the broiler for 1 minute to refresh. Make-Ahead: Prepare the custard mixture (steps 2-3) up to 4 hours in advance and keep refrigerated. Fill and broil just before serving. Variations: For a gluten-free version, use gluten-free tart shells. Substitute lemon zest for orange for a different citrus note. Serving Suggestion: Garnish with a thin slice of fresh orange or a dusting of powdered sugar.
