Ingredients:
- 200g high-quality spaghetti
- 2 liters water
- 1 tbsp sea salt
- 100g guanciale, cut into small batons
- 3 large egg yolks
- 1 large whole egg
- 60g freshly grated Pecorino Romano
- 2 tsp coarsely cracked black pepper
Instructions:
- Place the guanciale in a cold skillet over medium-low heat. Render the fat slowly until the pork becomes golden and shattering-crisp. Remove the pan from the heat entirely once finished.
- In a small mixing bowl, whisk together the 3 egg yolks, 1 whole egg, grated Pecorino Romano, and half of the cracked black pepper until it forms a thick, pale-yellow paste.
- Boil the spaghetti in salted water until 'molto al dente', approximately 1–2 minutes less than the package instructions. Reserve 1 cup of starchy pasta water before draining.
- Transfer the hot pasta directly into the skillet with the rendered pork fat (ensure heat is OFF). Toss thoroughly to coat every strand in the oil.
- Pour the egg and cheese mixture over the pasta while whisking or tossing vigorously. Add a splash of the reserved pasta water (2-3 tablespoons) to emulsify the sauce into a creamy custard consistency.
