Steam asparagus in one to two inches (two and a half to five centimeters) of water seasoned with one teaspoon salt until just cooked, about five minutes. Transfer steamed asparagus to an ice water bath to stop the cooking process and ensure bright green asparagus. Heat a frying pan over high heat and drizzle in the olive oil. Add the asparagus and blister. This can take around 10 minutes. You don’t want to stir it every minute, because you want it to make contact with the bottom of the pan with enough time for it to blister before it overcooks. Remove from heat.

Combine dressing ingredients in a small bowl. Drizzle over the asparagus just before serving.

If desired, serve with an oven-dried radish (see tip).
