In a small bowl, whisk together maple syrup, soy sauce, dijon mustard, chili powder, cayenne pepper and garlic. Pour or generously brush the glaze over the salmon, reserving 1 tablespoon for glazing once salmon is done. Bake for 15-20 minutes or until salmon is done and flakes with a fork. For every inch of salmon filet thickness, you’ll need to bake for 15 minutes. Usually 18 minutes is perfect for me.
