Creating Sweet Pea Soup is simple if you follow these straightforward steps:

1. Sauté Vegetables: In a large pot, heat the olive oil over medium heat. Add the chopped onion and sauté until it becomes translucent, about 5 minutes.
2. Add Garlic: Stir in the minced garlic and cook for an additional minute until fragrant.
3. Cook Peas: Add the sweet peas and vegetable broth to the pot. Bring to a boil, then reduce heat and let simmer for about 15 minutes.
4. Season: Stir in salt, pepper, and nutmeg, allowing the flavors to meld for 5 more minutes.
5. Blend: Using an immersion blender, puree the soup until smooth. If you don’t have an immersion blender, carefully transfer the mixture to a countertop blender and blend in batches.
6. Add Cream: Return the soup to low heat and stir in the heavy cream. Allow it to warm through, but do not let it boil.
7. Taste and Adjust: Taste the soup and adjust the seasoning if necessary.
8. Serve: Ladle the soup into bowls, and top with fresh mint or lemon zest as a garnish if desired.

This straightforward process gives you a creamy, delightful Sweet Pea Soup that will surely impress anyone.
