Fettuccine Alfredo

Cook pasta according to package instructions in a large pot of boiling water and salt. Add heavy cream and butter to a large skillet over medium heat until the cream bubbles and the butter melts. Whisk in parmesan and add seasoning (salt and black pepper). Let the sauce thicken slightly and then add the pasta and toss until coated in sauce. Garnish with parsley, and it's ready.

Cooking notes

Pasta scales beautifully — water and salt should track the dry weight; sauce can be reduced slightly if you scale up beyond a single pan.

For volume-to-weight conversions of any ingredient — flour, sugar, butter, salts — use the ingredient converter. To translate the recipe's oven temperature between °C, °F and gas mark, see the temperature converter.

When you scale this recipe up or down, remember that cooking time does not scale linearly. A doubled cake takes longer, but not twice as long; a doubled soup takes roughly twice as long. The cooking-time guide gives sensible starting estimates by dish geometry.
