Overview

Cloves are the dried, unopened flower buds of the evergreen tree Syzygium aromaticum, native to the Maluku Islands (the Spice Islands) of Indonesia. They have a pungent, sweet, and numbing flavor with a high concentration of eugenol, the compound responsible for their characteristic aroma and mild anesthetic effect [2]. Cloves are used whole or ground in both sweet and savory cooking across many cuisines.

Origin and history

Cloves are native to a small group of islands in eastern Indonesia, historically called the Maluku Islands or Spice Islands [1]. Archaeological evidence suggests cloves were traded in the Middle East as early as 1700 BCE, and they reached Europe via the Silk Road and later through Portuguese and Dutch colonial trade routes. The Dutch East India Company (VOC) maintained a monopoly on clove production for much of the 17th and 18th centuries by restricting cultivation to a few islands [1]. Today, the largest commercial producers are Indonesia, Madagascar, Tanzania (including Pemba Island and Zanzibar), India, and Sri Lanka [3].

Varieties and aliases

  • Whole cloves – dried flower buds, used in stocks, braises, and studded into onions or citrus.
  • Ground cloves – powdered form, used in baking and spice blends.
  • Clove oil – essential oil extracted from buds, leaves, or stems, used in dentistry and flavoring.
  • Chinese name: ding xiang (丁香).

Culinary uses

Cloves are used sparingly due to their intensity. In whole form, they are often stuck into onions or ham for braising, or added to poaching liquids, mulled wine, and spiced punches. Ground cloves appear in spice blends such as Chinese five-spice and Indian garam masala. Whole cloves also perfume master stocks and braised meats in Chinese cooking, and are used in some Mexican sweet preparations, such as capirotada and ponche navideño, as well as in panela-based syrups in Central American cuisines.

Cross-cuisine context

Cloves have no direct analogue in any single ingredient. Their warm, numbing quality is sometimes paralleled by Sichuan peppercorn in Chinese cuisine, though the flavor profiles are entirely different. In many sweet preparations, cloves function similarly to cinnamon and allspice as a primary aromatic in syrups and festive drinks.

Notes for cooks

  • Use whole cloves sparingly: one or two can perfume an entire pot of liquid. Remove before serving, as biting into a whole clove is unpleasant.
  • Ground cloves lose potency quickly. Buy whole cloves and grind as needed for the strongest flavor.
  • Clove oil is highly concentrated. A single drop can overwhelm a dish. Dilute in fat or alcohol before adding.
