Editor’s note: The theme of Gohan Lab is to help people make simple, tasty “gohan” (meals). * * * People who enjoy eggs and pasta will love this week's recipe for spaghetti carbonara, which balances the rich sauce created by adding cheese or cream to eggs, thick noodles matching the sauce, and the black pepper that spices it all up, to create the popular flavor. Carbonara means “charcoal worker style,” named so according to one theory due to the coarsely grated black pepper used in it that resembles powdered charcoal. The ingredients we'll use follow the Italian recipe. But this week’s recipe offered by Kuniaki Arima, the chef who supervised the cooking aspect, adopts the “kama-tama udon” style (boiled udon noodles fresh from the pot mixed with raw eggs). The sauce and pasta are mixed in a bowl and the hot noodles naturally half-cook the egg. The dish is foolproof.
