The main ingredients. Yes, you are supposed to separate the asparagus into three groups: tips, middles, and ends. No, it's not required to stack them into pyramids. I'm just extremely OCD.
Each part of the asparagus is added at different times and cooked in different ways. I used celery instead of leeks. I didn't have any leeks.
The tender part of the celery simmering in butter and olive oil with diced onion.
After everything is cooked and combined, it's all liquefied in the food processor. I made enough to feed the Goslin family.
The seasonings and lemon juice are added during the final simmer. I took a few liberties to suit my own pallet. There's certainly more salt than called for.
