Mojo criollo — a marinade and sauce built from sour orange juice (naranja agria), garlic, cumin, and olive oil — is the foundation of Cuban cooking. It marinates pork (lechón asado), dresses yuca (boiled cassava), and functions as the all-purpose acid-fat-aromatic condiment of the Cuban kitchen. The sour orange (Citrus aurantium, also called Seville or bitter orange) was brought to Cuba by the Spanish — it is the same fruit used in English marmalade, but in Cuba it serves a completely different function: as a cooking acid rather than a preserve.
- **Sour orange is not regular orange juice with lime.** The flavour profile of naranja agria is uniquely complex — bitter, sour, floral, and aromatic simultaneously. The common substitute (half orange juice, half lime juice) approximates the acidity but misses the complexity. If you can source Seville oranges, do. - **The garlic must be mashed, not minced.** Crushed garlic (in a mortar or with the flat of a knife and salt) releases more allicin and more volatile compounds than minced garlic. The difference in a mojo is audible — the crushed garlic sizzles differently in the hot oil. - **Hot oil over the garlic.** The traditional technique: crush garlic and cumin, heat olive oil until shimmering, pour the hot oil over the garlic-cumin paste. The oil blooms the cumin and half-cooks the garlic in seconds. Then add the sour orange juice. This sequence matters — adding garlic to hot oil risks burning; pouring hot oil over garlic cooks it precisely.
