Allioli. Allioli. Allioli. I love how the vowels and lulling Ls roll off the tongue – softly and whimsically – almost like a child’s nonsense word. all-ee-oh-lee. It’s a melodic sound. Allioli is a Catalan version of classic aioli, and it differs fundamentally from Provençal aiolis in that it is made without egg yolk – offering just a combination of good quality olive oil, fragrant garlic and unrefined sea salt.
