This recipe was originally made with ramps, which is a wild onion which does not seem grow here and is really delicious and has a season about a month and a half long it seems. This is an approximation of that sauce made with items readily available here-baby leeks and scallions. The sauce is essentially a vinaigrette thickened up with lots of alliums and herbs, and is great for topping meats (this was first made for red wine marinated lamb chops) and fish, or being used on a salad made with flavorful sturdy lettuces such as romaine, Little Gems, and the like.
