Upside Down Apple Tarts

Upside Down Apple TartsRomulo Yanes
Jacques Maximin claims he never served these tartes fines aux pommes at Chantecler restaurant at the famed Hôtel Négresco. Jacques Torres, Maximins pastry chef for eight years, insists they were consistently on the menu. All that matters to us, though, is that the classic combination of warm apple and flaky pastry becomes new again in these light, simple tarts.
Cooks' notes:
•Pastry cream can be chilled up to 3 days. Stir before using.
•Pastry can be rolled out and cut 1 week ahead and frozen, tightly wrapped in plastic wrap. Do not thaw.
•Tarts can be baked 4 hours ahead. Reheat in a 350°F oven 5 to 10 minutes.
