Aioli” refers not only to the sauce made with garlic, egg yolks and olive oil, but also to a complete dish where the sauce is served with boned salt-cod, hard-boiled eggs, squid or snails and vegetables such as carrots, potatoes, artichokes and green beans.
2 egg yolks, preferably free range
1/4 teaspoon salt
pinch of English mustard or 1/4 teaspoon French mustard
1 dessertspoon (2 American teaspoons) white wine vinegar
8fl oz (225ml/1 cup) oil (sunflower or olive oil or a mixture) - We use 6fl oz (175ml/3/4 cup) sunflower oil and 2fl oz (50ml/1/4 cup) olive oil, alternatively use 7/1
1-4 cloves of garlic, depending on size
2 teaspoons chopped parsley
Put the egg yolks into a bowl with the crushed garlic, mustard, salt and the white wine vinegar (keep the whites to make meringues). Put the oil into a measure. Take a whisk in one hand and the oil in the other and drip the oil onto the egg yolks, drop by drop whisking at the same time. Within a minute you will notice that the mixture is beginning to thicken. When this happens you can add the oil a little faster, but don't get too cheeky or it will suddenly curdle because the egg yolks can only absorb the oil at a certain pace. Taste and add a little more seasoning and vinegar if necessary.
If the Mayonnaise curdles it will suddenly become quite thin, and if left sitting the oil will start to float to the top of the sauce. If this happens you can quite easily rectify the situation by putting another egg yolk or 1-2 tablespoons of boiling water into a clean bowl, then whisk in the curdled Mayonnaise, a half teaspoon at a time until it emulsifies again. Finally add the chopped parsley and taste for seasoning.
