Step 1

In a food processor, combine the garlic, chiles, ginger, cilantro, lime zest and olive oil and process to a paste; transfer to a large bowl. Whisk in the coconut milk and lime juice and season with salt.

Step 2

In a large soup pot, bring the lager to a boil over high heat. Boil until reduced to 1/2 cup, about 7 minutes. Add the mussels, cover and cook, shaking the pot a few times, until the mussels just begin to open, about 4 minutes.

Step 3

Uncover the mussels and stir in the coconut milk mixture. Cover and cook, shaking the pot a few times, until all of the mussels open, about 8 minutes. Spoon the mussels and broth into bowls and serve.
