““Here’s a trick to always have a bouquet garni ready: Take the green part of a leek (the part you usually throw away). Cut it into 3-inch pieces. Inside each leaf, place a branch of thyme, a laurel leaf, and a branch of parsley (these are examples—you can use whichever herbs you like best). Tie the bundle with a kitchen string. You can then freeze them in a resealable bag and take them out whenever you need them.””
