Surely, it was caprice that caused someone to spell Caprese this way:
Okay, here’s the deal: If you want “a sudden, impulsive, and seemingly unmotivated notion or action” (M-W), then that’s caprice. When you want a delicious salad made with mozzarella, tomato, and basil, that’s an Insalata Caprese. Which happens to be one of MRP’s favorite salad combinations. Um, excuse me, I’m feeling a little hungry . . .
