Three peppers at three heat levels means you build the sauce rather than just making it hot, and that's the actual lesson — jalapeño for body, serrano for the middle, habanero for the sting at the back. Chef Emily was clear about gloves and about not leaning over the pan, both of which somebody ignored to their considerable regret. It keeps for weeks in the fridge, so you leave with something you'll use rather than a single meal.
