Emulsions
Ajoblanco
Ajoblanco · A foundational Andalusian cold emulsion from Málaga, Spain, made by blending soaked stale bread with blanched raw almonds, raw garlic, cold water, and olive oil into a silky, pourable white suspension. It functions as a reusable emulsion base that can be served as a chilled soup, dressed as a sauce, or thinned further for other applications.
The formula
2 parts soaked bread : 1 part blanched almonds; emulsify with ~4 parts water to 1 part olive oil
Bread-to-almond volume is roughly 2:1; water typically equals or slightly exceeds the bread volume; olive oil is emulsified in at roughly one-quarter the water volume.
Identity
- Cold no-cook emulsion
- White/blonde color (no tomato, no pepper)
- Almond-thickened rather than dairy-thickened
- Bread-bound rather than gelatin-bound
- Andalusian origin, specifically Málaga
- Garlic-forward with sherry-vinegar acidity
- Vegan-compatible base
Ingredients
| Base | Day-old rustic white bread, crusts removed, soaked in cold water | Provides the body of the emulsion; must be thoroughly soaked so it disintegrates fully. |
| Base | Blanched raw almonds (Marcona preferred) | Supply emulsifiable fats and the signature almond flavor; skins must be removed for a pure white result. |
| Liquid | Cold filtered water | Both soaks the bread and thins the emulsion to pouring consistency. |
| Fat | Extra-virgin olive oil (preferably Andalusian) | Slowly streamed in to create a stable emulsion; provides mouthfeel and gloss. |
| Aromatics | Raw garlic cloves | Provides the characteristic pungent bite central to the preparation. |
| Seasoning | Fine sea salt | Brightens and balances the emulsion. |
| Acid | Sherry vinegar | Traditional in Málaga versions; sharpens and lifts the rich almond-bread base. |
| Garnish | Seedless green grapes, halved | Classical accompaniment that adds sweet, fresh contrast; not part of the base itself. |
Method
- 1Soak torn day-old bread in cold water until fully softened, then gently squeeze out excess water.Softened bread disperses evenly into the emulsion and contributes starch that stabilizes the suspension; removing excess water prevents dilution.
- 2Combine soaked bread, blanched almonds, garlic, and salt in a blender or food processor; blend to a coarse paste.Breaking down the almonds releases their oils and creates the particulate network that will hold the emulsion.
- 3With the machine running, slowly stream in the olive oil in a thin, steady stream.Gradual incorporation allows the oil to emulsify into the aqueous almond-bread phase rather than separating out.
- 4Add cold water in stages, blending on high, until the mixture reaches a smooth, pourable, cream-like consistency.Water thins to working texture while the high-speed blending shears the almond solids fine enough to read as smooth.
- 5Blend for several minutes at high speed, then pass through a fine mesh strainer if a perfectly silken texture is desired.Extended blending fully ruptures almond cells; traditional Andalusian cooks strained through cloth for an ultra-fine result.
- 6Season with sherry vinegar and additional salt to taste, then chill thoroughly.Acidity and salt are added after emulsification so they sharpen rather than disrupt the suspension; chilling thickens and melds flavors.
Techniques that matter
Bread soaking
Hydrates the crumb so it integrates fully and contributes starch that helps stabilize the emulsion.
Slow oil streaming
Mimics the action of a mortar and is required to build a true oil-in-water emulsion rather than a broken mixture.
High-speed blending
Shears almond solids small enough to feel creamy without dairy; the longer the blend, the silkier the result.
Optional chinois or cloth strain
Traditional method for removing any remaining almond grit for a luxurious, glossy texture.
Cold maturation
Resting chilled lets the bread starches swell and the flavors round out; the base is always served cold.
Variations & derivatives
Ajoblanco MalagueñoMálaga, Andalusia
The canonical version: blanched Marcona almonds, rustic bread, garlic, olive oil, sherry vinegar, finished with green grapes.
Ajoblanco with grapes and moscatelAxarquía (Málaga)
Traditional coastal variant that may be garnished with Moscatel grapes or a drizzle of Moscatel wine.
Pine-nut forward ajoblancoModern Andalusian kitchens
Replaces a portion of the almonds with pine nuts for a sweeter, more delicate nut profile.
Apple ajoblancoContemporary Spanish kitchens
Adds green apple to the blender for a sharper, fruitier note while keeping the emulsion structure.

Substitutions
- Blanched Marcona almonds → Regular blanched almonds — Most accessible substitute; flavor slightly less sweet and floral.
- Sherry vinegar → White wine vinegar or champagne vinegar — Provides similar bright acidity; sherry's nutty depth is lost.
- Day-old rustic white bread → Toasted fresh white bread — Toast first to remove moisture, then soak; works but less traditional.
- Raw unblanched almonds → Blanched almonds — Must be blanched (skin removed) for the characteristic pure-white color; unblanched yields speckled, slightly bitter result.changes result
- Extra-virgin olive oil → Lighter olive oil or neutral oil — Possible but loses the Andalusian flavor signature.changes result
Troubleshooting
Grainy or gritty texture
Insufficient blending time or almonds not processed long enough to release their oils → Blend on high for several additional minutes and/or pass through a fine mesh strainer.
Too thick
Too much bread or too little water in the final blend → Loosen in small increments with cold water, blending after each addition, until pouring consistency.
Olive oil separates or emulsion looks broken
Oil was added too quickly or the base was too cold/dry to incorporate it → Add a small piece of soaked bread and re-blend from low to high, streaming remaining oil slowly.
Bitter or harsh flavor
Garlic too aggressive, almonds not blanched, or vinegar over-added → Balance with more soaked bread, a touch more water, and a pinch of salt; tame raw garlic by removing the green germ.
