6 Tbs. (3/4 of a stick) of the the butter in a large skillet over medium-high heat. When it begins to bubble, saute the fish fillets about three minutes on each side, or until golden brown. Move the fish to a pan in the oven at 250 degrees to stay warm while finishing the sauce.
Add the remaining butter to the pan, along with the lemon juice, Worcestershire, and vinegar. Whisk the pan ingredients to blend, and bring to bubbling again.
Add the almonds and lower the heat a little. Cook until the almonds just begin to turn a little brown at the edges. Spoon the sauce and the almonds over each trout fillet. Garnish with lemon wedges, parsley, and/or snipped green onion.
