Start by peeling asparagus (see tips in the article) and rinse wild garlic.
Heat butter and oil in a large pan (large enough to lay whole asparagus inside).
When fat is hot, place asparagus in the pan, roast for about 3 minutes on one side over medium heat, then flip asparagus and add the wild garlic leaves.
Roast for a few more minutes, add ¼ to ½ glass of water and cover. Asparagus will continue to gently cook, flavors of wild garlic will develop.
Cook for a few more minutes until asparagus become tender. The cooking time depends on thickness of asparagus.
Notes
The main steps: Heat oli-butter, peel asparagus. Pan fry, that's all.
