DJ Olsen likes Pellegrino for a hangover and soup. He's making a fish soup using market ingredients. After you make the stock, add pre-cooked potatoes, fennel, fish, clams, and/or mussels. The dish takes only a few minutes to make.
David West has domestic truffles at the Santa Monica Farmers Market. Use them by shaving thin slices into butter, potatoes, and scrambled eggs. Be sure not to cook them as they'll lose their flavor. Instead, put them over hot food.
