Mayonnaise

• 1 tablespoon Dijon mustard
• 2 egg yolks
• 150 ml olive

Whisk together the eggs and mustard in a blender. Keeping the blender on, slowly pour all the oil through the pouring hole in the lid, until the mixture is smooth and pale yellow. Blend in the vinegar and taste – you may need to add either oil or vinegar according to your palate.
