Juniper berries are the fleshy seed cones of a hardy evergreen conifer: piney, resinous and faintly citrus, best known in gin and in the game and cabbage dishes of northern Europe.
What it is¶
Juniper "berries" are not berries at all. Juniper is a conifer, and what we call the berry is a female seed cone whose scales have fused and turned fleshy, so it looks and behaves like a small fruit. The cones take two to three years to ripen on the bush, starting hard and green and finishing a dusty blue-black with a pale waxy bloom. A single shrub usually carries green and ripe cones at the same time, which is why pickers traditionally beat the branches over a cloth and let the unripe ones stay put.
Common juniper, Juniperus communis, is the species used in food. It grows from Scotland and Scandinavia to the Himalayas and across northern North America, from windswept heath to mountain scrub. Most commercial juniper is still gathered from wild plants, especially in the Balkans.
Dried berries are 5–10 mm across, slightly soft and sticky inside, with three small hard seeds. They are almost always sold whole, and should be crushed just before use.
Origins and history¶
Juniper has been burned, chewed and brewed for a very long time. The smoke was used across Europe for purification and to fumigate rooms, and the berries appear in classical and medieval herbals as a medicine for a long list of complaints — claims that should be read as history rather than advice.
Its best-known role came in the Low Countries in the 16th and 17th centuries, when distillers flavoured malt spirit with juniper to make genever, the Dutch word for the plant (from the Latin juniperus, via French genièvre). English soldiers and traders brought a taste for it home, the name was clipped to "gin", and the London gin craze of the early 18th century followed. Juniper remains the one botanical a spirit must taste of to be sold as gin in the UK and EU.
In the kitchen, juniper belongs to the cold north and the mountains: Alpine and German game cookery, Scandinavian cured fish and meat, and the sauerkraut of Alsace and central Europe.
Flavour and aroma¶
Crush a berry and the smell is immediately of pine forest and gin: sharp resinous alpha-pinene, then a softer citrus-peel note from limonene, a woody, faintly peppery edge and a surprising sweetness from the sugars in the flesh. Cooked, it becomes rounder and less medicinal, and it has a particular talent for cutting the richness of fatty meat and the gaminess of venison, boar and duck.
It is strong. Four to six berries flavour a casserole for four; a dozen will make it taste like a cleaning product.
In the kitchen¶
Juniper works best in slow, savoury dishes with fat and acidity.
- Game and red meat: crush 6–8 berries with black pepper, thyme, garlic and salt as a rub for venison, or add them to a red-wine marinade. German Sauerbraten and many Alpine venison stews use juniper with bay and cloves.
- Cabbage: sauerkraut and Alsatian choucroute garnie are classically seasoned with juniper and caraway. A few berries also improve braised red cabbage.
- Pork and charcuterie: terrines, pâtés, brined pork belly, cured hams and sausages.
- Cured fish: a few crushed berries in a salt-and-sugar cure for salmon or trout, alongside dill, is a Scandinavian habit.
- Poultry: duck and goose, and stuffings for both.
- Sweet uses are rarer, but a couple of berries in a pear or plum compote, or in a syrup for gin cocktails, work well.
💡 Crush, don't grind
Press berries under the flat of a knife or bash them lightly in a pestle-and-mortar. They are too sticky to grind cleanly in an electric mill, and a coarse crush releases the oils without turning them into paste. Fish whole berries out before serving if you can; biting one is startling.
Add juniper at the start of slow cooking so it has time to mellow. In marinades, 12–24 hours is plenty.
Buying and storing¶
Buy whole berries that are plump, dark and slightly yielding when pressed, with a strong smell when crushed. Hard, shrivelled, brownish berries are old. Stored airtight, away from light and heat, they keep their aroma for a year or more — better than most spices, because the oils are sealed inside the flesh. Ground juniper fades quickly; avoid it. See storing-spices.
Substitutes¶
There is no true substitute. A tablespoon or two of gin added to a sauce or marinade gives the closest effect. Failing that, a small sprig of rosemary with a bay leaf supplies the resinous, herbal side, though not the sweetness. In sauerkraut, extra caraway is a reasonable fallback.
Pairs well with¶
Venison, boar, hare, duck, goose, pork, cabbage, apples, pears, red wine, gin, black pepper, bay, thyme, rosemary, caraway, allspice, cloves, garlic and orange peel.
Growing your own¶
Common juniper is extremely hardy and happy on poor, free-draining soil in full sun. It is dioecious — male and female flowers grow on separate plants — so a berry-bearing female needs a male nearby to set fruit, and garden-centre cultivars are often chosen for shape rather than berries. Expect a wait of several years before a crop, and two to three years for each cone to ripen. Pick only the dark, dusty cones.
Health and safety¶
Only Juniperus communis berries should be used for cooking. Some other junipers, notably savin (Juniperus sabina), are toxic, so do not forage from an ornamental shrub you cannot identify. Juniper in culinary amounts is widely eaten, but concentrated juniper preparations are traditionally advised against in pregnancy and for people with kidney disease.
