You’ve probably noticed that the asparagus stem is harder than the tip. Tips therefore require less time to cook. An asparagus steamer allows you to place the vegetables upright in a metal basket. This is placed in boiling water, which allows the asparagus to be evenly cooked. The same effect can be achieved by using an empty food can, open at both ends. Cook the asparagus upright so the heads don’t spoil.
Asparagus will store longer in the fridge if you wrap it in a damp cloth and place in a plastic bag.
