Classic New England-Style Coleslaw — a traditionally tangy salad — is a favorite for picnics and barbecues.
1 large egg
1 cup sour cream
1 tablespoon all-purpose flour
6 tablespoons cider vinegar
1 tablespoon sugar
1 medium onion, quartered
1/2 cup celery leaves, loosely packed
1 bay leaf
1 medium-size green cabbage, shredded
Salt and freshly ground black pepper
1. Whisk the egg and sour cream in a small saucepan. Add the flour and stir over medium heat until the mixture bubbles and thickens slightly.
2. Meanwhile, combine the vinegar, sugar, onion, celery leaves, and bay leaf in another saucepan and boil, uncovered, at a gentle bubble for 5 minutes. Strain the liquid, then whisk it into the sour cream mixture.
3. Place the shredded cabbage in a large mixing bowl. Pour on the dressing and toss to combine. Season with salt and pepper. Cover the bowl and refrigerate until thoroughly chilled.
