Oyster & Crab Pan Roast

In a large saucepan, melt the butter. Add the lemongrass, shallots, garlic, chiles and a generous pinch of salt. Cook over moderately high heat, stirring, until the shallots are softened and just starting to brown, about 2 minutes. Add the beer and boil until evaporated, about 3 minutes. Add the tomatoes and kaffir lime leaves, then crush the tomatoes with a wooden spoon. Simmer over moderately low heat until most of the liquid has evaporated, about 5 minutes. Add the coconut milk and simmer over moderate heat, stirring occasionally, until thickened, about 15 minutes.

Add the crabmeat, oysters, pollack roe and lime juice to the saucepan and cook over low heat until warmed through, about 2 minutes. Season with salt. Transfer the pan roast to bowls and serve.
