Aioli is simple to make, and there are endless variations to keep it interesting. Try a dollop on roasted potatoes, serve as a dip with fries, spread some on a sandwich, or serve it alongside roast beef. Aioli is traditionally prepared with olive oil (unlike mayonnaise, which is ussully made with more neutral-tasting oil like canola). The Olive oil adds fruitiness and tempers the garlic's intensity.
