½ cup sour cream
¼ cup mayonnaise
2 Tablespoons lemon juice
2 Tablespoons + 1 teaspoon sugar
1 teaspoon salt
¼ teaspoon black pepper
1 large English cucumber
1 small red onion
1 sprig fresh dill (optional)
1. Combine sour cream, mayo, lemon juice, sugar, salt, and pepper.
2. Wash and peel cucumbers. Cut into slices 1/4" thick. Peel and slice onion thinly, about 1/8" thick. I used a mandoline slicer for this.
3. Toss cucumber slices, onion, and dill (if using) in cream sauce.
4. Cover with plastic and chill at least 2 hours, or overnight to let the flavors develop.
