I am very saddened to say that perhaps deep frying the beans for 45 seconds makes the difference. I am also convinced that the rice vinegar is now mandatory in the recipe! I am not convinced that the hoisin needs to be in there, but I can give it another shot. My next step....try this sauce recipe without deep frying the beans first! Aren't you proud? I have now learned to follow a recipe word for word the first time! Whatever I try....Szechuan beans will never be off our menu!
