Blanch the asparagus in salted boiling water for about 2-4 minutes, depending on thickness of the stems. Using tongs, remove the asparagus and plunge them in iced water for a couple of minutes to stop the cooking processes and preserve the colour. The cooking water will be packed with flavours, do not throw it away, but instead use it to cook rice, pasta or in stock and soup recipes.
You can grill asparagus using a grill pan, oven grill or barbecue. The direct high heat adds a distinctive charred flavour to the asparagus. This is great to add extra flavours into any dish. To do so, season and brush your asparagus with olive oil to prevent them from drying. Then place them on the hot grill and cook for about 3-4 minutes or until lightly browned but with a slight crunch. To maintain the green colour, you can first blanch your asparagus in salted boiling water for 1 minute and then grill for 2 minutes.
