Allspice vs Juniper
The short answer
Both are dried berries used whole in braises and cures, which is where the confusion starts and ends. Allspice is warm, sweet and clove-like from eugenol. Juniper is resinous and piney from pinene — the flavour of gin — and is used with game, pork and cabbage for exactly that reason. They are not related and cannot be exchanged; a juniper berry in a jerk marinade tastes of the wrong forest.
Side by side
| Allspice | Juniper | |
|---|---|---|
| Botanical identity | Pimenta dioica (L.) Merr. | Juniperus communis L. |
| Part used | berry, fruit | berry, fruit |
| Origin | The Greater Antilles and Central America, with Jamaica the historic and still the most reputed source. | Circumpolar across the northern hemisphere, with the widest natural range of any conifer. It is native to most of Europe, northern Asia and North America rather than originating in any one place. |
| Flavour notes | warm, sweet, clove-like, cinnamon, peppery, woody | woody, bitter, citrus, sweet, cooling |
| Heat | Scoville does not apply | Scoville does not apply |
| Flavour | Sweet, warm and gently pungent, reading as clove first, then cinnamon, then a faint pepperiness. It is milder and rounder than clove and much easier to use in quantity, which is why it can carry a dish where clove can only accent one. | Piney, bittersweet and astringent, with a clean sharpness at the front and a lingering bitterness. It is assertive and easily overdone — a dish either tastes of juniper or does not contain it — and the bitterness is what makes it work against fat and against strongly flavoured meat. |
| Aroma | Warm and sweet, clove-dominated with clear cinnamon and a light peppery edge. The impression of several spices at once is genuine rather than suggestible — the oil contains the compounds that dominate each of them. | Resinous and coniferous, sharply green with a citric lift and a faint sweetness behind. It is the smell of gin, which is the reference point most people have for it, and the association runs in that direction rather than the other. |
Which should you buy?
Allspice
Buy whole. Allspice keeps unusually well in the berry, grinds acceptably at home, and is used whole in a great many of its traditional applications — pickling, brining, braising — where it needs to be retrievable. Ground allspice also loses the specific thing that makes it worth having: as the lighter aromatics go, it converges on a flat clove note, and at that point you may as well have used clove.
Juniper
Whole, and buy a small jar. Juniper is soft, resinous and volatile: it clogs a mill, so it is crushed by hand at the moment of use, and it fades faster than most whole spices, so a large jar will be hard and aromatic-free long before it is finished. Squeeze a berry through the packaging if you can — give is the single best indicator, and a jar that rattles has nothing left in it. Most kitchens use juniper a few times a year, for a braise or a cure, and a small jar replaced annually is the honest pattern.
