1/2cupheavy cream
1/2teaspoonsalt
1/4teaspoonblack pepper
Fresh chivesfinely chopped, for garnish
A handful of leekthinly sliced and fried crisp, for garnish, optional
Instructions
Melt the butter in a large pot over medium heat and add the leeks and onion, cooking for 6 to 8 minutes, stirring often, until soft but not browned.
Add the potato and broth, bring to a boil, then reduce to a simmer and cook for 18 to 20 minutes, until the potato falls apart when pressed with a fork.
Blend the soup with an immersion blender, or in batches in a stand blender, until completely smooth.
Stir in the cream and season with the salt and pepper, then warm through over low heat without letting it boil.
Pour the soup into small glasses, filling each about three quarters full.
Top each with a pinch of chopped chives and a few crisp fried leek strands if using, and serve warm.
Good to Know
Make the soup base up to 2 days ahead and keep it covered in the fridge; reheat gently over low heat and pour into glasses right before guests arrive.
