Traditional Catalan Garlic and Oil Sauce (Allioli a la Catalana)
José's tips: It's hard to think that, when you start crushing the garlic, it will ever turn into something as dense and smooth as allioli. But don't give up. It's worth the extra time and effort to see the oil and garlic come together before your eyes. Just make sure you're adding the olive oil slowly, drop by drop. Keep moving the pestle around the mortar in a circular motion and keep dreaming of the thick, creamy sauce at the end of it all.
