Place salmon fillets on a foil lined rimmed baking sheet and season with salt and pepper. Transfer 1/2 cup glaze to a small dish and brush on top of salmon. Broil salmon until glaze is bubbling and fish is opaque throughout, 5-10 minutes, depending on thickness; brush remaining glaze over fillets. Serve salmon along with watercress and lemon wedges.
