Lentils With Garlic and Herbs

Ingredients
Instructions
In a large saucepan, combine lentils with carrot, onion, and celery (or sauté the vegetables first for a deeper flavor, optional)
Tie garlic cloves and herbs into a cheesecloth sachet and add to pot (optional, but if opting out make sure the herbs are finely chopped)
Cover lentils with at least 2 inches of water, season generously with salt (the water should taste as salty as you like your food to be), and set over medium heat.
Bring to a simmer, then reduce heat to medium-low and cook at a bare simmer until lentils are just tender enough that you can smash one against the roof of your mouth with your tongue, about 25 minutes (begin checking around 15 minutes, then continue checking until lentils are perfectly cooked).
Add a handful of ice cubes or a generous splash of cold water to the bean pot to lower the water's temperature and halt cooking.
The lentils can be refrigerated in their cooking liquid at this point for up to 2 days before continuing with recipe.
Discard the herb sachet before continuing.
To Finish: In a large saucepan, melt butter over medium heat until foaming. Add finely diced vegetables and cook, stirring, until barely tender, about 2 minutes. Add drained lentils along with just enough of their cooking liquid (about 1/4 cup) to moisten slightly. Bring to a simmer, then cook until lentils are heated through and enough liquid has evaporated that the lentils are coated in a creamy glaze.
Add vinegar 1 teaspoon at a time until the lentils have a pleasant bright flavor (it should taste like a light contrasting tang, but not strongly sour).
Season with salt and pepper. Stir in parsley and serve warm, either with rice or on their own.
