In a pot over high heat, bring the water and stock to a boil. Add the snow peas to the pot, reduce the heat to low, and simmer until tender, about 5 minutes. Add the sweet peas and cream. Let simmer for 1 minute, then pour the soup into a blender. Blend the soup on high speed until smooth, about 3 minutes. Pass the soup through a fine strainer and season, to taste. Garnish with creme fraiche and chives.
