To prepare vegetable mixture:
Soak white beans overnight. Strain and
cook with thyme in fresh water. Cool on sheet pan. Preheat oven to 225 degrees.
Combine all vegetables (excluding tomatoes) and roast in oven until soft.
Cool. Combine white beans, lemon juice, tomatoes, more thyme and garlic.
Season to taste with salt and white pepper. Set aside.
To prepare salmon:
Sear salmon in a oil-drizzled skillet
over medium heat, turning half-way through. Salmon is done when it flakes
easily with a fork. Remove from heat.
To prepare lemon foam:
Bring lemon juice, water, zest, shallot
and sugar to boil. Remove from stove and add bloomed gelatin. Leave at
room temperature. Pour mixture into a whip canister (charger), shake, and
refrigerate
To assemble:
Place a mound of vegetable mixture on
the center of each serving plate. Lay seared salmon across, skin-side up.
Top with a dollop of lemon foam. Garnish with fresh herbs, if desired.
