About Swiss Chard

Best fermented in two parts: the crisp stems pickle like a mild celery, while the leaves ferment like a tender green. High water content makes the leaves wilt quickly, so they are often packed with the chopped stems for structure. A good way to preserve a glut of chard.

Technique

Separate leaves from stems. Cut stems into 1cm pieces and chop the leaves. Salt the combined weight at 2.5% and massage briefly, or brine the stems at 2.5% (25g salt per liter) and add the wilted leaves. Pack below the brine and ferment 7-14 days at 65-72°F; the stems stay crunch-forward.

Salt level notes at 2.25%

Use when you want a mild pickle — e.g. pepper jars for sandwich garnish. At this salt level, monitor daily and refrigerate at first taste-check-pass.

Safety: Safe range for lacto-fermentation. 2% is the most common default for cabbage, kimchi and pepper mash.
