Aromatic bases & spice pastes
aliño
aliño · A classic Spanish emulsified seasoning of olive oil, vinegar or citrus, and raw garlic — used as a marinade, finishing sauce, or salad dressing across Spain. The garlic is traditionally pounded to a paste with salt before the oil and acid are incorporated, creating a loose emulsion that coats proteins, vegetables, and bread. Regional variants include chimichurri, mojo, and adobo.

The formula
3 parts olive oil : 1 part acid (by volume); 1–3 garlic cloves per 50 ml total liquid
The garlic-salt paste is prepared first. Oil is drizzled in slowly while whisking to form a loose emulsion. No egg; stability comes from vigorous whisking and enough salt to lower interfacial tension.
Identity
- Olive oil as the dominant fat — never neutral oil
- Raw garlic, not cooked, crushed to a paste with salt
- Sherry vinegar or fresh citrus juice as the acid
- Slow incorporation of oil into acid while whisking to emulsify
- Seasoned immediately with salt, adjusted before serving
Ingredients
| Fat | extra-virgin olive oil | 120–150 ml; use a fruity, peppery Spanish EVOO for best results |
| Acid | sherry vinegar or fresh lemon juice | 40–50 ml; vinegar gives depth, citrus gives brightness. Classic Spanish aliño uses sherry vinegar. Choose one. |
| Aromatics | garlic cloves, peeled and crushed to a paste | 2–4 cloves (6–12 g); the paste is the flavor core. Pound with salt in a mortar for best texture. |
| Seasoning | flaky sea salt | ½–1 tsp; dissolves into the garlic paste and is essential for emulsification and flavor. |
| Flavor | pimentón (smoked or sweet) | ¼–½ tsp; not universal, but deeply common in Castilian and Extremaduran aliño. Add with caution — burns easily. |
| Aromatics | flat-leaf parsley, finely chopped | 1–2 tbsp; stirred in at the end for freshness and color. Common in many regional forms. |
Method
- 1Pound or grate the garlic with the salt to a smooth, wet paste in a mortar or on a board.Salt crystals lacerate garlic cells efficiently, releasing allicin and forming a bound paste. A food processor is acceptable but produces a coarser, less emulsifiable result than a mortar.
- 2Add the vinegar or citrus juice to the garlic paste and whisk vigorously.The acid begins to extract flavor compounds from the garlic and creates the aqueous phase of the emulsion. Whisking introduces air and begins emulsification.
- 3Add the olive oil in a very slow, thin stream while whisking continuously.Slow incorporation allows small oil droplets to form and remain suspended in the aqueous phase. Adding oil too fast causes the droplets to coalesce and the emulsion to break.
- 4Taste and adjust seasoning — more salt, acid, or garlic as needed.The ratio is a starting point. Final seasoning depends on what the aliño will coat. Add herbs and pimentón only after seasoning is balanced.
- 5Let the aliño rest 5–10 minutes at room temperature before using.Salt continues drawing moisture from garlic, deepening flavor. The emulsion stabilizes slightly as it rests.
Techniques that matter
Pestle-and-mortar grinding
Creates a bound garlic-salt paste with ruptured cell walls, maximizing allicin release and giving the smoothest, most emulsifiable base. A grater or microplane is an acceptable modern substitute.
Slow oil incorporation / whisking emulsification
Without egg or gum, aliño is a temporary emulsion stabilized by salt, vigorous whisking, and acid. Slow addition of oil is what makes it work.
Taste-and-adjust seasoning
Aliño is a seasoning component, not a finished sauce. It must be calibrated to the dish it will season, which requires tasting and correcting before use.
Variations & derivatives
aliño de perejil (mojo verde style)Canary Islands / Canarian cuisine
Cilantro or parsley is blended with the garlic, oil, vinegar, and sometimes a green chili into a bright green sauce. The structure and technique are identical; herbs are the primary variable.
aliño de cilantro / huacatayPeru, Mexico, and Andean regions
Cilantro or huacatay paste replaces or supplements the parsley. Common in coastal Peruvian cuisine as a finishing aliño for grilled fish.
aliño con pimentón / aliño extremeñoExtremadura, Castilla y León
Smoked pimentón is whisked into the vinegar before emulsification. Gives a deep red color and smoky backbone. Common for cochifrito (fried lamb) and grilled pork.
chimichurriArgentina, Uruguay
A direct descendant of the Spanish aliño, scaled up in herb volume (parsley dominant) with oregano, and often with red pepper flakes. Same fat-acid-garlic structure.
adobo (as paste/marinade base)Mexico and the Philippines
Chili, garlic, vinegar, and oil blended to a paste and applied to meats before cooking. The aliño principle applied with chilis as the dominant aromatic.
Used in these dishes
Substitutions
- sherry vinegar → red wine vinegar or fresh lemon juice — Red wine vinegar is the closest in acidity and body. Lemon juice brightens but changes depth. Either is acceptable.
- extra-virgin olive oil → high-oleic sunflower oil — Use only in extremis. The grassy, peppery character of EVOO is structurally part of aliño's identity. Neutral oil produces a technically correct but culturally hollow result.changes result
- fresh garlic → garlic powder — Garlic powder lacks the allicin development and cell-wall rupture of fresh. Use at ¼ tsp per clove as a last resort only.changes result
Troubleshooting
Emulsion breaks and oil pools on the surface
Oil added too quickly, insufficient whisking, or not enough salt to lower interfacial tension → Add 1–2 tsp cold water and whisk vigorously, or start over: pound garlic-salt paste again, add vinegar, and re-emulsify with slow oil incorporation. A pinch of mustard powder also stabilizes.
Garlic flavor is harsh or too raw
Garlic not sufficiently pounded; large pieces remain; or wrong garlic-to-acid ratio → Use the finer side of a grater or continue pounding. Allow the aliño to rest 10–15 minutes — allicin compounds mellow with time. Do not add more oil to mask the flavor.
Aliño tastes flat or one-dimensional
Under-seasoned or acid not balanced by salt → Add salt gradually, tasting between additions. If acid is missing, a few drops of vinegar sharpen and open all other flavors. A tiny amount of sugar or honey can round harsh acidity.
Pimentón turns bitter and dark
Added directly to hot oil or whisked into oil that is already warm → Always add pimentón to the vinegar first, not the oil. Whisk it into the vinegar phase before emulsifying. Use cool oil, not warm.
