Preparation: Drain and rinse canned green peas (or pod and rinse fresh peas). Mince garlic and slice onion. In a preheated pot over medium-low heat, sauté the onion and garlic in butter with a little bit of cooking oil for four minutes.
Sauteing: Stir in green peas, salt, white pepper, garlic powder, and a chicken stock cube. Add 2 cups of water and bring to a boil. For canned peas, simmer for 15-20 minutes; for fresh peas, simmer for 25-30 minutes. Peas will turn dark green if using fresh peas.
Blending: Use an immersion blender to finely blend the peas. Add fresh cream and blend until smooth, adding water if needed. Enjoy the soup hot, with buttered toast or garlic baguette.
