Usually in the standard recipe. Often in many versions. Sometimes in some kitchens, or a cross-contact risk.

Diets

• Not vegetarian: guanciale or pancetta is the backbone, and PDO Pecorino Romano uses lamb rennet.
• Not halal or kosher: cured pork, often with its rendered fat in the sauce.
• Not gluten-free unless made with gluten-free pasta cooked in fresh water.

Recipes change from kitchen to kitchen. If you have an allergy, confirm every ingredient with the restaurant before you order.

What is carbonara?

Carbonara is a Roman pasta dish made from five things: pasta, egg, Pecorino Romano cheese, black pepper and guanciale (cured pork cheek). The sauce is an emulsion of egg, cheese and pork fat that turns glossy in the heat of the just-drained pasta. The Roman version has no cream, garlic, onion or peas. It belongs to the same family as gricia, amatriciana and cacio e pepe.

What's in it

• Pasta: spaghetti is the default; rigatoni, tonnarelli and mezze maniche are common in Rome.
• Guanciale: cured pork cheek, cut into strips and fried until crisp. Pancetta (cured belly) is a frequent stand-in, and bacon turns up abroad.
• Egg: yolks only, or yolks plus some whole egg, beaten with the cheese and pepper.
• Cheese: Pecorino Romano, a hard sheep's milk cheese. Some cooks blend in Parmigiano Reggiano.
• Black pepper: plenty of it, freshly ground.

Outside Italy, carbonara often arrives with cream, onion, garlic, mushrooms or peas. Meat-free "carbonara" made with courgette (zucchini) is a modern variation, not the classic.

Allergens and diets

Assume egg, milk and gluten in every carbonara. The egg is the sauce, and it's barely cooked: the pasta's heat thickens it without scrambling it, so the yolk stays close to raw. If you've been told to avoid undercooked egg, that matters as much as an allergy does.

Milk comes from the Pecorino, and sometimes from Parmigiano or, outside Italy, cream. Sheep's milk proteins are very similar to cow's milk proteins, so a "no cow's milk" request doesn't help someone with a milk allergy. Gluten comes from the wheat pasta, and fresh pasta adds more egg.

Gluten-free pasta is easy to find in Italy, where coeliac (celiac) awareness is high. Ask whether it's boiled in its own water and drained separately, because pasta water and colanders are usually shared. Carbonara isn't vegetarian, halal or kosher: the pork is the point, and Pecorino Romano is made with animal rennet.

On the menu

In Rome you'll see spaghetti alla carbonara or rigatoni alla carbonara in the primi (pasta) section of the menu. A plate is a full portion for one. Alla gricia is the same dish without egg, cacio e pepe is just Pecorino and pepper, and amatriciana adds tomato to the guanciale. Abroad, "carbonara" can mean almost anything creamy with bacon, so ask what's in the sauce.
