Coat a large saucepan with olive oil. Add the onion, celery and garlic and bring to a medium heat. Season with salt and sweat until the vegetables are very soft and aromatic, about 8 to 10 minutes.

Remove the tips from the asparagus and reserve. Cut the stalks of the asparagus into 1-inch lengths and add them to the pot. Sweat for 2 to 3 minutes. Add the potatoes and the stock. Taste for seasoning and add salt, if needed (it will). Bring to a boil, then reduce heat and simmer for 20 minutes.

On a separate burner, bring a small pot of well salted water to a boil over high heat. Have a small bowl of well salted ice water on standby. Cook the asparagus tips in the boiling water for 2 to 3 minutes. Remove them from the boiling water and plunge them immediately into the ice water. When the tips are cool, remove them from the water, pat dry and reserve.

In a blender or with an immersion blender, puree the asparagus stock mixture. Strain through a mesh strainer, if desired. Taste and adjust the seasonings, if needed. Chill.

Garnish with the reserved asparagus tips and crumbled goat cheese. Springtime delicious!
