Store-bought mayonnaise just doesn't compare to the flavor of homemade aïoli. However, if you're short on time or concerned about using raw egg (see cooks' note, below), you could substitute prepared mayo: Just omit the egg yolk and oil, and stir together with remaining ingredients until combined well.
This recipe is an accompaniment for Poached Halibut with Saffron Orange Aïoli.
Active time: 15 min Start to finish: 15 min
Cooks' notes:
• The egg yolk in this recipe will not be cooked, which may be of concern if there is a problem with salmonella in your area. • Aïoli can be made 1 day ahead and chilled, covered.
