Step 1: STEP 1

Step 2: Put a large saucepan of water on to boil.

Step 3: STEP 2

Step 4: Finely chop the 100g pancetta, having first removed any rind. Finely grate 50g pecorino cheese and 50g parmesan and mix them together.

Step 5: STEP 3

Step 6: Beat the 3 large eggs in a medium bowl and season with a little freshly grated black pepper. Set everything aside.

Step 7: STEP 4

Step 8: Add 1 tsp salt to the boiling water, add 350g spaghetti and when the water comes back to the boil, cook at a constant simmer, covered, for 10 minutes or until al dente (just cooked).

Step 9: STEP 5

Step 10: Squash 2 peeled plump garlic cloves with the blade of a knife, just to bruise it.

Step 11: STEP 6

Step 12: While the spaghetti is cooking, fry the pancetta with the garlic. Drop 50g unsalted butter into a large frying pan or wok and, as soon as the butter has melted, tip in the pancetta and garlic.

Step 13: STEP 7

Step 14: Leave to cook on a medium heat for about 5 minutes, stirring often, until the pancetta is golden and crisp. The garlic has now imparted its flavour, so take it out with a slotted spoon and discard.

Step 15: STEP 8

Step 16: Keep the heat under the pancetta on low. When the pasta is ready, lift it from the water with a pasta fork or tongs and put it in the frying pan with the pancetta. Don’t worry if a little water drops in the pan as well (you want this to happen) and don’t throw the pasta water away yet.

Step 17: STEP 9

Step 18: Mix most of the cheese in with the eggs, keeping a small handful back for sprinkling over later.

Step 19: STEP 10

Step 20: Take the pan of spaghetti and pancetta off the heat. Now quickly pour in the eggs and cheese. Using the tongs or a long fork, lift up the spaghetti so it mixes easily with the egg mixture, which thickens but doesn’t scramble, and everything is coated.

Step 21: STEP 11

Step 22: Add extra pasta cooking water to keep it saucy (several tablespoons should do it). You don’t want it wet, just moist. Season with a little salt, if needed.

Step 23: STEP 12

Step 24: Use a long-pronged fork to twist the pasta on to the serving plate or bowl. Serve immediately with a little sprinkling of the remaining cheese and a grating of black pepper. If the dish does get a little dry before serving, splash in some more hot pasta water and the glossy sauciness will be revived.
