Pit the cherries, place in a pot, add lemon juice, sugar, and cinnamon. Wrap cloves in gauze and tie a knot, place in the pot with cherries (this makes it easier to remove cloves before blending the soup), add thyme.
Pour in water, mix, and bring to a boil. Cook over low heat covered for about 7 minutes. Remove cloves and blend into a cream, cool, and chill in the refrigerator. Serve with sour cream and thyme leaves.
