Step 1In a food processor, puree the beefsteak tomatoes and salt. Pour the puree into a large bowl lined with a double layer of cheesecloth. Tie up the tomato puree with the cheesecloth and then tie it to a wooden spoon and suspend it across a large pot to collect the liquid. Or you can use a large chinois. Drain overnight in the refrigerator.
Step 1Bring a medium pot of water to a boil. Add salt (about 1 tablespoon per quart of water) and blanch the cherry tomatoes in the water, about 1 minute. Refresh in ice water. Peel the skin off (this is easy if the tomatoes are scored), cut them in half and place them in a bowl.
Step 2Season with one-quarter teaspoon salt, the pepper and the olive oil. Mix in 1 tablespoon chive blossoms, and let the tomatoes macerate at room temperature.
Step 3In a medium saucepan, bring the tomato consomme to a boil and add one-quarter cup of sage flowers, reserving the rest for garnish. Remove the consomme from the heat and cover. Let the consomme infuse for 8 minutes. Taste and infuse for longer if necessary; the sage should not be too strong but should have an aromatic flavor.
Step 4Season the consomme with salt and pepper to taste, strain out the flowers and keep the consomme warm.
Step 5In a steamer (or a saute pan fitted with a rack) filled with 2 cups of water, add the white wine, peppercorns, basil, lemon and shallot. Bring to a boil on high heat. Continue to boil, covered, for 5 minutes.
Step 6Season the salmon fillets lightly with sea salt and white pepper. Steam the fillets over the prepared liquid on medium-high heat for about 5 minutes.
Step 7Place each salmon fillet in the center of a soup plate. Spoon macerated tomatoes over the top and sprinkle with the reserved sage flowers and chive blossoms. Ladle the consomme around the salmon and serve immediately.
