Sweating mirepoix
Is it necessary to take the time to sweat mirepoix? If it’s a dish that is cooked for a long time, won’t the flavors of these vegetables make their way into the sauce regardless?

Great question, Dee. When you sweat those foundational vegetables - whether it's just onions and garlic, or a classic mirepoix, or something else - what is happening has to do with the vegetables being exposed to direct, more intense heat (in contrast to the gentler heat of a simmering sauce, soup or stew). When you just have your mirepoix in the pan, those ingredients are getting up to the neighborhood of 300°F, which is when we start to see browning occur via the Maillard reaction and caramelization (remember that there are plenty of sugars in things like onion and carrot), two chemical processes that catalyze new flavor and aroma compounds. Once those flavors have been developed, you can move on to adding liquid - at which point the temperature drops to a maximum of 212°F - which distributes those complex flavors through the sauce, soup or stew. Does that make sense? - April D.
