2 tablespoons unsalted butter
4 slices bacon (about 4 ounces), cut into small dice
1 large leek (about 3/4 pound), dark-green parts cut off and saved for stock, leek halved lengthwise, cleaned, and cut into small dice
2 celery ribs (4 ounces), cut into small dice, with 1/4 cup picked tender leaves reserved for garnish
2 bay leaves
1 tablespoon fresh thyme leaves, roughly chopped
1/8 teaspoon cayenne pepper
1 pound Yukon Gold potatoes, unpeeled, cut into medium dice
1/4 cup dry white vermouth
One (8-ounce) bottle clam juice (see note)
1 1/2 cups heavy cream
3/4 pound cleaned razor clam meat, cut into small dice
2 teaspoons fish sauce (such as Red Boat brand), optional
Kosher salt
Tabasco sauce or other hot sauce of your choice, for serving
Buttery crackers (such as Ritz), broken up, for garnish

In a Dutch oven, combine butter and bacon and cook over medium heat, stirring occasionally, until the bacon begins to brown and crisp, 7 to 10 minutes. Using a slotted spoon, transfer half the bacon to a paper towel–lined plate; reserve for garnish. Add the leek to the remaining bacon in the Dutch oven and cook, stirring, until tender, about 3 minutes. Add the diced celery, bay leaves, thyme, and cayenne and cook for 1 minute. Add the potatoes and increase the heat to medium-high. Cook the potatoes for 3 minutes, stirring occasionally. Add the vermouth and bring to a boil, scraping up any brown bits from the bottom of the pot. Add the clam juice and just enough water to cover the potatoes (about 8 ounces/240ml). Bring to a boil, reduce to a simmer, then cook until the potatoes are tender. Add the cream, return to a simmer, then simmer for 10 minutes. Bring the chowder to a boil, turn off the heat, add the razor clam meat, cover the pot, and let stand for 1 minute; this will be enough to gently poach the clam meat without letting it become rubbery. Add fish sauce, if using. Season with salt. Ladle soup into bowls and top with reserved bacon and celery leaves. Serve, allowing diners to add hot sauce and crumbled crackers to their bowls as desired.
