A recipe for cucumber salad with dill sour cream from Rachael Ray and a recipe for cold cucumber soup with cherry tomato confetti from MyRecipes are examples of recipes that involve cucumbers, onions and sour cream. Both recipes are simple and require only a few steps.
To prepare the cucumber salad, peel 5 cucumbers, slice them lengthwise, and remove the seeds. Cut the cucumbers into 1/4-inch-thick pieces, and combine them with 2 teaspoons of salt in a colander. Let the cucumber juices drip into a bowl for at least one hour. Stir 1 1/2 cups of sour cream, 1/4 cup of apple cider vinegar, 1/4 cup of chopped fresh dill and 1/2 tablespoon of sugar together in a large bowl. Incorporate 1 sliced red onion and the drained cucumbers, and add pepper to taste.
To prepare the cucumber soup, peel and de-seed 5 cucumbers, and roughly chop them. Remove the seeds from 1 jalapeño pepper. Put the cucumbers and jalapeños into a food processor, along with 1/2 cup of chopped cilantro and 1/4 cup of chopped onion. Pour in 1/4 cup each of freshly squeezed lime juice, fat-free butter milk and reduced-fat sour cream, and season the mixture with 1 teaspoon of salt and 1/2 teaspoon of black pepper. Blend the ingredients to make a smooth soup, and garnish the soup with 1 cup of halved cherry tomatoes before serving it.
