Notes
- Key limes are smaller, tarter and more aromatic. Ordinary (Persian) limes work but taste milder: about 4 of them give the 120 ml of juice needed.
- The lime juice partly sets the custard on its own — the short bake finishes it safely.
- Traditionalists insist on a graham cracker crust and no green food colouring.

More American recipes
- Baked Chicken and PotatoesBone-in chicken thighs and drumsticks rubbed with smoked paprika and olive oil and roasted at 220°C on a bed of potato chunks, whole garlic cloves, lemon wedges and rosemary. Fat from the crisping skin drips into the potatoes, which get 10 more minutes on their own while the chicken rests, and the soft garlic and roasted lemon are squeezed into the pan juices that coat the potatoes.
- Beef StewThe American beef stew: chuck dusted in flour, browned hard in batches and simmered low in beef stock with tomato paste, Worcestershire sauce, thyme and bay until it yields to a spoon. Potatoes, carrots and celery go in partway so they cook through without collapsing, the flour thickens the gravy as it simmers, and peas are stirred through at the end.
- Braised Short RibsBone-in beef short ribs seasoned and seared hard, then cooked slowly in the oven in reduced red wine and beef stock with carrots, onion, celery, garlic, thyme, rosemary and bay until the meat slips from the bone. Strained, skimmed of fat and boiled down, the braising liquid turns into a dark, glossy sauce, and gremolata or parsley scattered over at the end cuts the richness.
