On top of a layer of aluminum foil and plastic wrap (enough to make a pouch), put the salmon on a baking sheet skin-side down. Pat the top dry with paper towels. Combine the coriander, mustard and cumin seeds in a small saute pan over low heat and toast, stirring constantly until fragrant, about 2 minutes. Remove, let cool slightly and coarsely grind in a coffee grinder.
Spread the chipotle over the top of the salmon fillet. Sprinkle the ground spices, lime zest and cilantro over and press into the flesh. Combine the salt and brown sugar in a bowl, drizzle with the tequila and then spread evenly over the salmon. Tightly wrap the salmon in the plastic wrap and aluminum foil. Place another baking sheet on top of the salmon and weigh down with bricks wrapped in foil or a heavy cutting board. Refrigerate for 48 hours.
Remove the salmon from the refrigerator and scrape off the curing ingredients. When cured, the fish should have a raw appearance and a firm but not hard texture. Slice the salmon against the grain paper thin and serve with accompaniments of choice.
Combine the vinegar, lime juice, sugar, salt, coriander seeds, mustard seeds and peppercorns in a small saucepan over high heat. Cook until the sugar and salt is dissolved. Remove from the heat and let cool for 5 minutes.
Put the onions in a medium bowl, pour the vinegar mixture over and toss to coat. Cover and refrigerate for at least 1 hour and up to 48 hours before serving.
Combine the cream cheese, goat cheese, milk and salt and pepper to taste in a food processor and process until smooth and fluffy. Scrape into a bowl and fold in the scallions and dill.
