Spaghetti alla Carbonara

Pasta and pork

• 360 g spaghettoni, bronze-die extruded (De Cecco, Mancini or Martelli); rigatoni also works
• 200 g guanciale, single ~3cm slab, rind removed, diced into 8mm lardons

For the sauce

• 6 large egg yolks, pasture-raised, at room temperature
• 70 g Pecorino Romano DOP, aged 8 months minimum, finely Microplaned (60g for sauce, 10g to finish)
• 20 g Parmigiano Reggiano, 24-month minimum, finely Microplaned
• 4 g black pepper, Tellicherry or Sarawak, coarse-cracked and dry-toasted

For the water

• 7 g coarse sea salt, per litre of pasta water (half the usual rate)
• 500 ml reserved pasta water, set aside before draining

Mise en place

1. 1

   Pull the yolks and Pecorino from the fridge 30 minutes before starting — cold yolks tighten the emulsion temperature window dangerously. Set a large covered pot of water (4L) on high heat.

2. 2

   Trim the rind from the guanciale and dice into 8mm lardons — batons, not small cubes, which over-crisp before the fat releases. Microplane both cheeses into a fine snow and weigh after grating.

   8m

   Tip: Coarse grating leaves visible cheese specks and refuses to emulsify smoothly.

3. 3

   Coarse-crack the pepper in a mortar (a few twists short of a powder) and toast it dry in a small pan over medium heat for 30–40 seconds until aromatic. Toasted pepper shifts the aroma from sharp to warm-floral.

Render the guanciale

1. 4

   Put the diced guanciale into a cold, dry, heavy stainless or carbon-steel pan and set it on low-medium heat. Work it for 8–10 minutes, stirring every 90 seconds, until the lardons are amber-gold at the edges but still tender in the centre.

   The cold start is essential — guanciale dropped into a hot pan seizes its proteins before the fat liquefies, leaving leathery edges and under-rendered interiors. Pure crunch reads as bacon, the wrong dish.

   Cold-Start Fat Rendering

   Tip: Aim for crisp outside, yielding inside.

2. 5

   Strain the rendered fat through a fine sieve into a small jug — you should have around 60–70ml. Keep it warm (above 50°C so it doesn't congeal). Reserve the lardons on a warm plate.

Cook the pasta

1. 6

   When the water boils, salt it lightly at 7g per litre — it should be subtly salty, not seawater, because the guanciale and Pecorino are already aggressive. Add the spaghettoni, stir for the first 90 seconds to prevent sticking, then leave alone.

   Pasta Water Starch Emulsion

   Tip: Stirring early releases the most starch; the water should turn visibly cloudy.

2. 7

   Cook to 2 minutes under the packet's al dente time. The pasta will finish cooking in the sauce, absorbing starchy water and acquiring gloss. Reserve 500ml of pasta water before draining.

   8m

   Don't drain — you'll lift the pasta straight from the water later, carrying its starch coating with it.

Build the sauce

1. 8

   In a heatproof bowl, whisk the 6 yolks with 60g of the combined cheeses and the toasted pepper until you have a thick, pale, ribboned paste — about 90 seconds of vigorous whisking. The paste should fall in slow ribbons and hold its shape briefly.

   Underwhisked yolks emulsify poorly — this paste is the foundation of the sauce.

2. 9

   Two minutes before the pasta is ready, set the bowl over (not in) the boiling water, with a wooden spoon across the rim so steam can escape. Whisking continuously, stream in the warm rendered guanciale fat in a thin thread, then ladle in 60ml of pasta water in three additions, whisking between each.

   Pull the bowl off as soon as the sauce coats the back of a spoon and a finger drawn through leaves a clean line — around 62–65°C. Above 70°C the yolk proteins coagulate into curds and the dish is dead.

   Tip: Streaming the fat in like a hollandaise builds the velvet fat-in-water emulsion before the water enters.

Marry and plate

1. 10

   Lift the spaghettoni straight from the water with tongs into the bowl with the sauce. Toss aggressively for 30–45 seconds, lifting the pasta high to incorporate air and cool slightly between cycles. Add a 30–50ml splash more pasta water if the sauce tightens too quickly. Fold in two-thirds of the reserved guanciale at the very end.

   Tip: You're aiming for a sauce that flows on the plate and slowly tightens around the strands as it sits.

2. 11

   Twirl portions into a tight nest in warmed bowls. Top with the remaining guanciale, a generous shower of the reserved 10g cheese, and a final crack of pepper. Serve within 60 seconds.

   Carbonara waits for no one — the emulsion tightens noticeably after two minutes off the plate.
