That’s pasta Alfredo in the photo, not carbonara. The bacon is just a little extra for the carnivores in the family. You’re still thinking it’s carbonara? I know, they look so similar. But this really is pasta Alfredo.
What’s the difference between carbonara and pasta Alfredo anyway?
Thesauce of pasta carbonara is made with beaten raw eggsand grated cheese (Pecorino, traditionally). The hot noodles are thrown in and tossed until the eggs emulsify into a creamy mixture. That’s carbonara. No cream in the sauce. Just eggs and cheese.
The sauce of pasta Alfredo is butter and cheese. Nothing else. Butter is melted in a pan and hot noodles are tossed in.
Grated cheese goes in next and they are all tossed together until the cheese melts. If the sauce is too stiff, you add some of the water in which the pasta was cooked. No cream.
But why are there so many recipes of both carbonara and pasta Alfredo with cream in them? Well, that may be attributed to the “commercial” version of these pasta dishes. Cream is cheaper than cheese. Cream is easier to work with than raw eggs.
