Winter Green Sauce
This is a good way to make use of those unnecessarily large bouquets of parsley that we get at our supermarkets, as well as fennel fronds that usually go to waste.
Ingredients
Preparation
Step 1
Put the scallions, fennel leaves, and parsley in the bowl of a food processor or a mini-chopper, and process until finely chopped. Smash the garlic clove, peel it, and chop the flesh. Sprinkle on about 1/4 teaspoon salt, and mash it with the garlic, using the flat of a big knife, smearing it back and forth until you have a paste. Or this can be done with a mortar and pestle. (In fact, the whole sauce can be made with a mortar and pestle—good exercise for your upper-arm muscles, Julia Child would say.)
Step 2
Back to the food processor: Scrape the garlic paste in, and pour in almost all the olive oil and most of the juice of the quarter-lemon. Process again until almost puréed, scraping down the sides as necessary. Stop and taste. Add more salt and a few more drops of lemon juice, if you think they are needed. Transfer the sauce to a small jar, scraping it all out with a rubber spatula, and float the remaining olive oil on top. Refrigerate, and use within a week; otherwise, freeze. If you’re using just a few tablespoons, float more olive oil on top before refrigerating again, to help preserve the color and freshness.
