What do American recipe terms mean in a UK kitchen?

Most American recipes work fine in a UK kitchen once the vocabulary is translated. The genuine traps are few but they matter: the cup measure, which is a volume being used where UK cooks expect a weight, and a handful of words that exist in both dialects meaning different things.

Step by step

1. Translate the heat words.Broil means grill — the element at the top of the oven, food close to it. Grill in American usage means barbecue, over coals or gas outdoors. So an American recipe saying 'grill the steak' means barbecue it, and 'broil the steak' means put it under your grill. Getting these two backwards is the most common confusion.
2. Translate the equipment words.Skillet = frying pan. Dutch oven = heavy lidded casserole. Sheet pan, half sheet pan, cookie sheet, jelly roll pan = baking tray, with the half sheet roughly a standard large UK oven tray. Broiler pan = grill pan. Saran wrap = cling film. Parchment paper = baking paper. Aluminum foil = foil.
3. Translate the ingredient words.All-purpose flour = plain flour. Confectioners' or powdered sugar = icing sugar. Superfine sugar = caster. Light brown sugar = light soft brown. Heavy cream = double cream (close enough). Half-and-half has no UK equivalent — use half single cream, half whole milk. Cilantro = coriander leaf. Zucchini = courgette. Eggplant = aubergine. Scallions = spring onions. Rutabaga = swede. Molasses = black treacle.
4. Handle butter in sticks.One US stick is 4 oz, which is 113g, and the wrapper is marked in tablespoons. Half a stick is about 57g, two sticks about 227g. American butter is usually unsalted by default, so a recipe calling for butter plus salt is expecting unsalted.
5. Treat cups with suspicion, especially for flour.A cup is 240ml of volume. For liquids that converts cleanly. For flour it does not, because how the flour is put into the cup changes the weight by up to 20% — scooped and packed against spooned and levelled. A cup of plain flour is roughly 120–130g, caster sugar about 200g, brown sugar packed about 220g, butter 227g. Use a proper conversion chart for baking, where the error matters.
6. Convert the temperatures.Fahrenheit to Celsius: subtract 32 and multiply by 5/9. The common ones: 350°F is 175–180°C conventional, 375°F is 190°C, 400°F is 200°C, 425°F is 220°C, 450°F is 230°C. Then reduce by about 20°C if you are using a fan oven, which American recipes almost never assume.
7. Watch the pint and the gallon.A US pint is 473ml against the UK's 568ml, and a US gallon is 3.79 litres against 4.55. For anything measured in pints or gallons — brines, stocks, drinks — assume the American measure and convert, or you will be out by 20%.

Tips

• American tablespoons and teaspoons are close enough to UK ones to ignore: 15ml and 5ml against the UK's 15ml and 5ml. Australian tablespoons are 20ml, which does matter in baking.
• If an American baking recipe gives grams as well as cups, use the grams. The author has done the conversion properly and it removes the packing problem entirely.
• Recipes written for US ovens rarely state whether the oven is fan-assisted, because most domestic US ovens are not. Assume conventional and drop 20°C for fan.

Common mistakes

• Reading 'grill' in an American recipe as your oven grill — It means barbecue. The result is food cooked from one side under a very close radiant element instead of over coals, which for thick pieces means burnt outside and raw inside.
• Measuring flour by scooping the cup into the bag — That packs the flour and can add 20% by weight. Spoon it into the cup and level it, or better, weigh it.
