PRESERVING GUIDE

Preserving Rosemary

Clip healthy rosemary sprigs in small amounts so the established plant can keep growing. The firm leaves suit air-drying in loose bunches or on a mesh rack, and frozen portions work well in cooked dishes. Keep dried rosemary away from moisture and light; discard any batch that becomes damp or mouldy.

Air Drying for Rosemary

General preservation or storage guidance

Preparation Several days to about two weeks; check regularly

Rosemary’s firm, resinous leaves air-dry well in small, loose bunches or on a mesh rack with good airflow.

Method

  1. Harvest sound rosemary sprigs after the dew has dried; discard discoloured or damaged growth.
  2. Rinse only if needed and dry the surface completely. Keep the leaves on their sprigs during drying so the small leaves are easier to handle.
  3. Tie a few sprigs loosely or spread them on a mesh rack in a warm, dark, well-ventilated place; protect them from rain and kitchen steam.
  4. Check regularly until the leaves feel dry and crumble when rubbed, and the small stems snap rather than bend.
  5. Strip the leaves from the dry stems, cool fully and pack airtight away from light and moisture. Discard if condensation or mould appears.

Storage

Airtight container in a cool, dark, dry place · Use while aromatic; discard damp or mouldy herbs
