    With the motor running, gradually drizzle in the oil until it emulsifies and you have a thick, creamy mayonnaise.

11. 11

    Beat the egg white to stiff peaks.

12. 12

    Mix half of the beaten egg white into the mayonnaise, then gently fold in the other half to make a very fluffy mousseline.

13. 13

    Serve the hot asparagus with the mousseline on the side.
