Culinary Notes

Chef's Note

This variety’s tight, pale heart delivers a clean sweetness and a cool crunch that doesn’t collapse when you dress it—raw slaw is where it really sings. Use it for fast pickling or fermentation: the texture holds, and the slight peppery edge plays beautifully with tang and fat.

Best Uses

thin-cut raw slaw that stays snappy under a vinaigrette
quick pickle or brined cabbage for clean tang and crunch
warm sauté or stir-fry where the leaves soften without turning mushy
fermented cabbage for a crisp, lively tang

Flavor Profile

cool, sweet cabbage core crisp, glassy crunch with a finely tender bite bright, lightly peppery cabbage finish

Frequently Asked Questions

What pests or diseases commonly attack Brassica oleracea var. capitata (Copenhagen Market cabbage), and what should I do?

Watch for cabbage worms (imported cabbageworm/diamondback moth) and aphids on the leaves; start control early by hand-picking larvae and spraying cabbage with an organic Bt (Bacillus thuringiensis) labeled for caterpillars. Also monitor for clubroot—stunted plants with swollen roots—by avoiding planting in the same spot and improving drainage; if clubroot appears, remove affected plants and don’t replant cabbage-family crops there for several years.

How often should I water Copenhagen Market cabbage during the main growing phase?

During head formation (roughly mid-season until harvest), keep the soil consistently evenly moist, not waterlogged. Aim for about 1–1.5 inches of water per week from rainfall plus irrigation, increasing during hot spells, and use mulch to prevent the soil from drying out between waterings (dry-wet swings can lead to head splitting).

How can I tell when Copenhagen Market cabbage is ready to harvest?

Harvest when the heads feel firm when gently squeezed and the outer leaves look full and tightly wrapped, typically around 75 days from transplanting/appropriate schedule. Heads should be at their mature size but still crisp—if they start to loosen or leaves separate, harvest immediately to avoid cracking from late-season stress.
