This was adapted from Margaret Johnson's cookbook, The New Irish Table. Her note from this recipe is as follows: "Related to both onion and garlic, leeks look like giant scallions but are the mildest of all of the three. Leeks figure prominently in recipes of Celtic nations from the earliest times, especially as a flavoring in soups or stews. They are often served as a side dish, as in this gratin from Marigold Allen, hostess of the Beeches Country House, County Antrim."
