Bring peas, stock and marjoram to the boil, skim and simmer covered for about 1 hour. Meanwhile clean and wash the carrots and spring onions and cut them diagonally into thin slices. Peel garlic and press it through a garlic press.
Dice the toast. Mash peas in the stock. Heat 20 g fat in a pot, sauté carrots and spring onions in it and deglaze with the soup. Bring to the boil and cook the vegetables for about 5 minutes.
Stir in crème-fraîche and season the soup with salt, curry and lemon juice. Heat the remaining fat in a pan and roast the toast cubes in it until golden brown. Finally stir in the garlic.
Serve the soup with croutons in deep plates. Garnish as desired with fresh marjoram.
