Harvesting Kale

When ready: Leaves are large enough to eat (15-20cm long for baby kale, 30cm+ for mature leaves). Dark green with firm texture. Lower leaves harvested first.

How to harvest: Snap or cut lower/outer leaves at the stem. Leave the growing tip and upper leaves to continue producing. Never harvest more than 1/3 of the plant at once. Twist and pull downward for clean removal.

Storing and preserving kale

How to keep it
  • Blanching and Freezing. Wash, remove stems. Blanch leaves in boiling water for 2 minutes. Ice bath, drain, squeeze out excess water. Pack into freezer bags, removing air. Freeze flat for easy portioning. Keeps: 10-12 months.
  • Kale Chips (Dehydrating). Wash, dry thoroughly, remove stems. Tear into pieces. Toss with olive oil, salt, and nutritional yeast or spices. Dehydrate at 55C for 4-6 hours until crispy. Store in airtight container. Keeps: 2-4 weeks (they go soft if stored longer).
  • Kale Powder. Blanch leaves 1 minute, ice bath, dry on towels. Dehydrate at 52C for 6-10 hours until completely crispy. Blitz in blender to fine powder. Store in airtight jar. Add to smoothies, soups, baking. Keeps: 6-12 months in airtight container in dark.
