Put the egg, sliced garlic, salt and 2 tablespoons of olive oil in a bowl or in the container of a hand stick mixer, and start blending everything together.
Now start adding the remaining oil slowly, in a thin, slow and steady stream. Keep blending while adding the oil.
When you have incorporated all the oil and the aioli has thickened, you can slowly add the lemon juice while still blending.
When all the lemon juice has been incorporated your aioli is ready.
Keep it in the fridge, in an air tight container until ready to use.
Recipe Notes
This recipe contains raw eggs, so be sure to use only very fresh eggs or pasteurised eggs. Consume the aioli within a couple of days and always keep it in the fridge.
