Peel the garlic and leave it in the vinegar overnight (I have never left it in the vinegar for the whole night and I don't think it really matters). Strain it and place it in a blender. 

Add the slices of bread that you have soaked in water and strained, 2 tbsp vinegar, the oil, the salt and a few tbsp of water. 

Blend to a smooth paste.
