About Fennel
The crisp bulb ferments into a softly anise-scented pickle that keeps a satisfying crunch. Fennel's licorice notes mellow as it sours, making it a favorite in Italian giardiniera and as a foil for rich foods. The fronds can be fermented along with the bulb for extra aroma.

Technique
Trim the stalks, halve the bulb, and slice 3-5mm or cut into wedges. Cover with a 2.5% salt brine (25g salt per liter); add a few fennel seeds or a strip of lemon peel if desired. Weigh below the brine and ferment 7-14 days at 65-72°F, then refrigerate while still crisp.
Salt level notes at 3.5%
Kimchi salting is a 2-stage process: 3.5-4% dry salt → 2-4 hour rest (flip halfway) → 3x rinse → paste application. The salt drawn into the water during rest is what rinses away. Final kimchi effective salt is ~2%.
Safety: Flavour-forward. Ferment will be slower; brine will taste salty. Good for pickles and hot-sauce mashes that need long shelf life.
