Annatto Flour: Combine all ingredients in a bowl and mix well. Pass through strainer and sift until no lumps exist.
Salmon: Preheat the oven to 350 degrees F.
Place the cedar boards tightly together on a 1/4 sheet pan or large jellyroll pan. Moisten the boards with water to saturate. Rub the boards with 2 tablespoons olive oil. Rub each salmon fillet with salt and pepper. Lightly coat with the annatto flour mixture. Place the remaining 2 tablespoons olive oil in hot saute pan. Pan sear the fillets until golden. Remove from pan and place on cedar boards. Place in the oven and cook for 7 minutes.
Chard: Wash the chard thoroughly and towel dry. Chop coarsely and set aside. In hot saute pan, add 2 tablespoons olive oil and the shallots. Saute until the shallots are soft, then add the chard. Cook until chard begins to soften, approximately 2 minutes. Remove from heat.
Bean Saute: In a hot saute pan, add the olive oil and heat. When the oil is hot, add the shallots and saute for 1 minute. Add the beans, salt, and pepper, and saute for 3 minutes. Remove from heat.
Saffron Orange Beurre Blanc: Combine white wine, minced shallot, and rice wine vinegar in saucepot. Reduce on medium heat until reduced by 50 percent. Slowly whisk in butter over very low heat until blended. Add saffron and orange zest and whisk in until blended thoroughly. Keep warm until service. Best to make last minute as it can separate.
This dish presents itself best if served in bistro bowls. Layer bottom of each bowl with equal amounts of Sauteed chard. Add 1/2 cup sauteed beans, and top with salmon fillet. Drizzle beurre blanc along the outside of chard. Garnish with citrus zest and capers, if desired.
