Do I really have to leave the pits in the cherries, or can I pit them before baking?
Leaving the pits in is traditional—the stones contain compounds that lend a subtle almond-like aroma and help the fruit hold its shape—but it isn’t mandatory. If you prefer easier eating, feel free to pit the cherries; just know they’ll release a bit more juice, so lightly flour or sugar-coat them and bake the clafoutis 5 minutes less to avoid a soupy center.
Can I make this clafoutis with frozen or canned cherries when fresh ones aren’t available?
Yes. You can substitute frozen or well-drained canned cherries; just thaw (or rinse) them thoroughly, pat dry, and toss with a teaspoon of flour or cornstarch to absorb excess moisture. Bake the clafoutis as directed, checking for doneness 5 minutes earlier, since the fruit will already be partly cooked and can make the custard set a little faster.
How do I store leftover clafoutis, and can I reheat it without drying it out?
Once completely cooled, cover the dish (or transfer slices to an airtight container) and refrigerate for up to 2 days; the custard is delicate, so avoid leaving it at room temperature for long periods. To reheat, tent the clafoutis loosely with foil and warm it in a 150 °C/300 °F oven for about 8–10 minutes, or microwave individual portions on medium-low power in 20-second bursts—just until the chill is off—to keep the texture moist and prevent the edges from drying out.
