Grilled Artichokes and Lemon with Spicy Garlic Mayonnaise

In general, this is an excellent way to cook and serve artichokes. The whole chokes are steamed, then cut in half, dechoked, and grilled, along with lemon halves. The halves are served with Spicy Garlic Mayonnaise, aka aïoli. I didn't make this, but tarted up some store-bought mayo with piment d'Esplette, garlic, and lemon juice. One half artichoke per person, a nice serving for a starter or side dish.

Small problem: The recipe says it serves four and asks for four artichokes. These are cut in half, each half grilled and served on small salad plates. But that makes eight servings. Before I realized this, I bought two artichokes for the two of us. I'll grill the remaining halves in the next days.
