Suddenly, the food would glow: Turnips and radishes would turn glossy. A broken pasta sauce would pull together. Meat and vegetable juices would swell with velvety body.

It was a last-minute touch of luxury, and it could be slipped into any dish because monté is nothing more than butter whisked into a little simmering water. That versatility makes it a great tool for home cooks too: You can whip up a batch in 10 minutes, flavor it with all sorts of seasonings (savory or sweet), and use it to add richness and polish to whatever you’re cooking: Steamed vegetables. Roast pork or potatoes. Filled pastas. Seared scallops. A platter of ruffly crepes. Think of it as butter in sauce form.
