@farmerman,
Here is the true carbonara recipe:
8 oz. Guanciale, cut into ¼" cubes (may substitute Italian 'pancetta' if guanciale is unavailable)
if necessary, 3 Tbsp. extra-virgin olive oil (highest quality available)
1 lb. regular-sized imported Italian dried spaghetti noodles (do not use 'spaghettini', 'angel hair' or thin spaghetti)
3 Tbsp. sea salt (for the pasta water), freshly ground, if possible
4 jumbo egg yolks only, at room temperature -- for a greater amount of servings, you might use 6 yolks!
1-¼ cups freshly-grated Pecorino Romano cheese (or half Pecorino Romano and half Parmigiano-Reggiano)
Freshly-cracked black pepper (generous amount)
Optional: An extra egg yolk per person to top each serving of carbonara to 'stir in'.
