Best storage conditions

Store fresh chervil cold, right around 32 to 40 degrees F, with high humidity near 95 percent so the leaves do not dry out. The crisper drawer of the refrigerator, where humidity is highest, is the ideal spot.

How long it keeps

Fresh chervil keeps only a few days, typically 3 to 5 days at best, and quality drops fast after that. For steady supply, most gardeners rely on succession sowings rather than long storage.

Storage methods

Refrigerate unwashed sprigs wrapped loosely in a barely damp paper towel inside a partly open bag or container. Alternatively, treat it like a bouquet by standing the stems in a glass with an inch of water, loosely tenting the leaves with a bag, and keeping it in the refrigerator. Rinse only just before use to avoid trapped moisture that speeds spoilage.

Freezing & preserving

Chervil loses much of its aroma when dried, so freezing is the far better choice: chop the leaves and pack them into ice cube trays topped with water or a little oil, then freeze and store the cubes in a labeled bag. You can also freeze whole sprigs flat on a tray before bagging them, or blend chervil into a herb butter and freeze it in portions. If drying, do it quickly at low heat and expect a much milder result. Chervil is a low-acid vegetable, so do not can it in plain water; only preserve it in a recipe specifically tested by the USDA Complete Guide to Home Canning or the National Center for Home Food Preservation, using pressure canning where a tested recipe requires it.

Tips

Add frozen chervil straight to finished dishes without thawing, since the leaves are too delicate to hold up to reheating. Because flavor is fleeting, preserve small batches and use them within a few months for the best taste.
