A delicious and easy dip is sour cream sweetened with confectioners' sugar and a little green Creme de Menthe. Make up ahead of time and allow sour cream mixture to chill overnight. Blueberries are going to be a tad more labor-intensive than strawberries because you have to pick through to remove any wayward stems and leaves. You can do this immediately after purchase and store, unwashed, in plastic bags in the refrigerator. Just before serving, rinse berries then toss with some light brown sugar and present along with them a pitcher of cold heavy cream to the side.
Guests help themselves to berries and pour on cream.
These are small, briny ripe olives that, to my knowledge, can't be purchased pit-free. Flavor dressing with salt to taste, minced fresh garlic or garlic powder, finely minced anchovies and herbes de Provence. But barring the use of this blend I usually opt for simply basil, marjoram and thyme. Another part of the salad you can do the day before is prepare hard-boiled eggs. Pour prepared vinaigrette over potatoes and refrigerate, covered.
