Step one
Heat the oil in a large heavy-bottom stockpot over medium-high heat until it’s shimmering but not smoking. Add the shallots and cook until they’re translucent but not browned.
Step two
Add the salt, then add the garlic and sauté for just 1 minute, until you can smell it. Add the wine, bring to a boil, and let boil for about 2 minutes before adding the stock.
Step three
Return to a boil, add the mussels, and cover the pot. As soon as the majority of the mussels open, which should take only a few minutes, turn off the heat. Any mussels that don’t open should be discarded.
Step four
Combine the crème fraîche and adobo or chipotles in a small bowl. Stir the chipotle mixture into the broth.
Step five
Serve the mussels immediately in individual bowls, dividing the sauce evenly over the mussels. Garnish each portion with a scattering of parsley. Enjoy with a hunk of bread.
