This lemon carbonara is wonderfully scented and flavored with springtime.
- 1 pound egg tagliatelle
- 3 tablespoons extra virgin olive oil ( EVOO )
- 1/3 pound pancetta, chopped into fine dice
- About 1 teaspoon coarse black pepper
- 6 cloves garlic, finely chopped
- 1 small Fresno chili pepper, seeded and finely chopped (optional)
- 1 bunch thin scallions, finely chopped, white and green parts separated
- Zest and juice of 1 large, ripe organic lemon, divided
- About 1 tablespoon fresh thyme
- 3/4-1 cup dry white wine
- A handful of flat leaf parsley, very finely chopped
- 3 large organic egg yolks
- Freshly grated Parmigiano Reggiano cheese (a couple of handfuls)
- Freshly grated Pecorino Romano cheese (a couple of handfuls)
- Shredded basil and diced yellow tomato, for garnish
Bring a large pot  of water to a boil for the pasta. When boiling rapidly, salt the water and cook the pasta to al dente. Heads up: reserve 1/2-3/4 cup of the starchy cooking water just before draining the pasta.
Heat a large skillet  over medium heat with the EVOO , three turns of the pan . Add the pancetta, season with black pepper and brown lightly. Stir in the garlic, chili pepper (if using), and the whites of the scallions, then zest the lemon over the pan  and stir in the thyme. Stir for 2-3 minutes, then add the wine, a couple turns of the pan, and reduce by half, 1-2 minutes. Reduce the heat to low.
When the pasta is about ready, beat the egg yolks with the reserved starchy water to temper them. Add the lemon juice, parsley and the greens of the onions to the pan.
Drain the pasta and add it to the pan. Turn off the heat, pour in the tempered eggs and sprinkle in a small handful of each of the cheeses. Toss vigorously for 1-2 minutes, until the sauce coats the pasta and it’s thick and shiny. Serve in shallow bowls  with a little extra cheese, shredded basil and diced yellow tomatoes on top.
