Fill a pot with water and bring to a boil. Add the broccoli florets and cook just until bright green and slightly softened, 1 to 2 minutes. Strain, immediately run cold water over the broccoli, and allow it to cool. Heat the oil in a small skillet over medium heat and add the cashews and pure maple syrup. Cook, stirring occasionally, until cashews are toasted, about 3 to 4 minutes. Stir together the mayonnaise, lemon juice, and sea salt in a small bowl. Combine the blanched broccoli, cooked bacon, raisins, and toasted cashews in a mixing bowl. Toss in the mayonnaise dressing and stir until everything is combined. Taste salad for flavor and add more lemon juice and/or sea salt to taste.
