Karasumi is the Japanese equivalent of Bottarga. It’s made by curing the roe sac of mullet in salt over the span of a couple weeks. This dries out the roe, intensifying it’s flavors while preserving it. Back in the day, it was even thought of as poor man’s caviar. Once cured, it’s briny and full of umami, with a waxy texture that clings to your teeth. Karasumi makes for a terrific canape and is consumed around the world with various accompaniments such as olive oil, garlic, and lemon. My favorite way of having it is sandwiched between two thin slices of daikon radish. The crisp, peppery radish makes for the perfect foil to wrap up the salty amber slivers of shaved karasumi. It’s a combo that goes great with a glass of your favorite alcoholic beverage, but I wanted to turn these flavors into more than just a tapa. Drawing some inspiration from the Sardinian classic, Spaghetti alla Bottarga, I decided to turn my karasumi daikon canape into a pasta. Rather than slicing the daikon, I grated it, which helps it incorporate into the pasta better. Since the daikon was relatively young and came with a beautiful green tuft of greens on top; I sautéed them in olive oil and tossed them along with the pasta and karasumi. It’s a rich decadent pasta that’s balanced out with a peppery sweetness coming from the grated daikon, and a just a hint of bitterness from the daikon greens. If you can’t find young daikon with greens still attached, watercress would make a great substitute.
