Peel the asparagus and sauté them in an oiled pan over high heat.
When they are colored, remove and pour the broth into the pan.
Add the miso and whisk until it is fully incorporated.
Now add the cubed butter and emulsify by stirring vigorously.
Finally, place the asparagus in the sauce and finish cooking, 5 minutes covered over medium heat.
The asparagus should still be firm and the sauce syrupy.
Serve with a little parsley and lime.
