Dried tomatoes, so intense on their own, can play a background role in a salad dressing. In this creamy ranch-style blend, they contribute sweetness, body, and an appetizing blush. They are hardly discernible, but the dressing would be less compelling without them. Spoon it over hearts of romaine, heirloom tomatoes, beets, or an old-fashioned iceberg wedge. It also makes a tasty dip for crudités.
Put the tomatoes in a small heatproof bowl, add the
boiling water, and let stand until softened, 10 minutes
or more. Drain in a sieve and squeeze to remove excess
moisture. Chop finely.
In a bowl, whisk together the mayonnaise and buttermilk,
then whisk in the green onions, dill, garlic, and 2
tablespoons chopped tomato. (If you have a little extra
tomato, mix with some extra virgin olive oil and spread on a
baguette slice.) Add the vinegar to taste, then season with
salt and pepper. If you used store-bought mayonnaise, you
may not need additional salt. Use the dressing immediately,
or cover and refrigerate for up to 3 days.
