Use fresh, ripe cherries: Sweet, ripe cherries give the crisp the best flavor. If your cherries are more tart, you can add a little extra honey.
Pit and halve the cherries first: This makes the crisp easier to eat and helps the cherries bake down evenly.
Stir the filling in a bowl: Mixing the cherries, honey, cornstarch, and lemon juice in a bowl first helps coat the fruit evenly before adding it to the baking dish.
Use certified gluten-free oats: Oats are naturally gluten-free, but they can be cross-contaminated, so use certified gluten-free oats if needed.
Let it cool before serving: The filling thickens as it cools, so let the crisp rest for 10-15 minutes before scooping.
