Unlike aioli, its Provençal cousin, allioli—one of the basic sauces in Catalan cuisine—is traditionally worked into an emulsion without eggs. This can be a tricky process to master. It helps to have all the ingredients, even the garlic, at room temperature and to hold the pestle lightly and use smooth, even motions.
