PRESERVING GUIDE

Preserving Basil

Harvest sound basil leaves regularly before plants become coarse or flower heavily, and use tender leaves fresh when possible. Air-drying needs a thin layer and moving air because leafy basil can retain moisture. The oil method here is freezer-only; do not leave fresh basil oil at room temperature.

Air Drying for Basil

General preservation or storage guidance

Preparation Several days air drying; check daily

Basil dries best in small batches with moving air; tender leafy herbs need particularly quick drying.

Method

  1. Harvest sound basil after the dew has dried; discard yellow or damaged leaves.
  2. Rinse only if needed and dry the surface completely; strip leaves from thick woody stems.
  3. Spread leaves in one layer on a mesh rack or use a pierced paper bag in warm moving air; large bunches can mould.
  4. Check daily until leaves crumble readily and stems snap; continue drying any soft or damp pieces.
  5. Cool fully, strip leaves 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
