In this article, you will learn everything there is to know about purple asparagus. We’ll cover where it comes from, how to cook it, and its health benefits.

What is Purple Asparagus?

Asparagus is a perennial plant with edible shoots that are either green or purple. The green shoots are most common, while purple asparagus is less common but still available in some areas. The purple color is caused by anthocyanin, a compound that is also responsible for the purple color of red cabbage, blueberries, and blackcurrants.

The shoots can be eaten both raw and cooked. Asparagus is an excellent source of vitamin K, manganese, and folate. It is also a good source of vitamin B6, potassium, vitamin E, and copper. The health benefits of asparagus are the same for both varieties. However, some of the anthocyanin in purple asparagus may be lost when cooked.

Where Does Purple Asparagus Come From?

The purple color of purple asparagus comes from anthocyanin, a plant pigment also found in red wine, blueberries, and blackberries. This plant pigment is what gives purple asparagus its vibrant color. Anthocyanin is also found in the soil, so to get purple asparagus, you need to grow it in soil that contains large amounts of iron and sulfur. These nutrients are found in soil in tropical and subtropical regions, so purple asparagus is more common in those parts of the world.

How to Cook Purple Asparagus?

As with any other type of asparagus, the best way to cook purple asparagus is to steam it. You can also boil or grill it, but as boiling will draw out more of the anthocyanin, it’s probably best to grill or bake the asparagus. There are a few things to bear in mind when cooking purple asparagus:

– Steaming is the best method for cooking purple asparagus. Boiling for too long will strip the purple color from the asparagus, so you should keep the cooking time to a minimum.

– Roasting works great for purple asparagus. You can either toss the asparagus with some oil and roast it in the oven, or you can put it on a baking tray lined with parchment paper and roast it in the oven.

– Purple asparagus cooks quickly so check it regularly to make sure you don’t overcook it.

– Purple asparagus should be eaten steamed or roasted. Boiling it in water will cause the anthocyanin to leach out and fade the color.
