TO MAKE THE HOISIN: Add the sesame oil to a small saucepan over medium heat. Add the ginger, garlic, and jalapeño, and stir until they start to brown. Then add the Chinese five-spice, stirring to incorporate. Whisk in the remaining ingredients and cover the pan to bring the mixture to a low rolling boil. Reduce heat to low and let the sauce simmer until thick, about 10 minutes. Let cool. Adjust sauce to taste with additional red miso. Reserve half of the sauce in a serving bowl and use the other half for brushing on the ribs during cooking.
