Cream of pea soup

3 tbsp. butter
1 onion (finely chopped)
400 g frozen peas
1/2 cup water
2+1/2 – 3 cups of milk
salt and freshly grated white pepper

Melt the butter in a a pan over low heat. Add the onion and saut̩ until soft, storing occasionally, around 5 minutes. Add the peas and water and bring to a boil, simmer on medium heat until the peas are tender (3 Р4 minutes for freeh peas, 10 minuter for frozen). Add 2+1/2 cup of the milk and season with salt and pepper. Bring to a boil, stirring and watching so it does not get burned or boil over. Remove from the heat and blend the soup with hand blender until very smooth. Bring the soup back to the boil and if it seems too tick, heat the remaining milk in a small pan and stir it to the soup.
