These Thai-inspired clams are salty, tangy, and rich from the coconut milk. If you can’t find fresh lemongrass, substitute a couple of sliced garlic cloves and the grated zest from half a lime instead. The broth won't have quite the same flavor, but it will still taste terrific.
Serve with garlic crostini or over rice, linguini, or ramen noodles. Try adding some thai red chili paste in with the shallots or substituting half of the clams with mussels.
