The bread (generally hard bread) is soaked overnight in order to soften it. The almonds and the garlic are mixed together (sometimes with vinegar) with a mortar and pestle until a white paste is formed. Finally water and olive oil are added and the mixture is beaten until it has an emulsion-like texture.
In some areas of Granada it is customary to eat it as an accompaniment to a "papa asá" (baked potato). When it is eaten in this way it is made slightly less thickly so as to be able to be drunk directly from a glass. In Málaga it is served with moscatel grapes and sometimes with pieces of other fresh fruit such as apple or melon. Nowadays ajoblanco is also commonly served with other combinations.
