Rocket is peppery and rather bitter. My daughter isn't a fan; I'm addicted to the stuff, especially when accompanying something slightly sweet like prawns or crayfish in a sandwich with lemon mayonnaise. Lovely in a salad with bacon, pomegranate and parmesan shavings with a bit of caesar dressing. Nigella Lawson does a very simple rocket pesto recipe in her A Taste of Summer cookbook that is absolutely fantastic. I made it once when we were holidaying with friends in Tuscany, and everyone loved it - I will never forget eating tagliatelle with rocket pesto out on the terrace of the villa with our friends, drinking cold Pinot Grigio, watching my daughter catching fireflies and listening to a nightingale singing. Magic.
