Asparagus is undoubtedly a true treasury of vitamins and minerals. They effectively prevent the formation of cancer, are largely responsible for the proper development of the fetus, and also support breastfeeding women. They are also recommended for people on a reduction diet, as 100 g of asparagus is only 18 kcal. Asparagus is also one of the most effective aphrodisiacs. What are their nutritional and therapeutic properties? Do they work as well on libido as caviar or lovage?
White, green and violet asparagus come from the same species, but their colour is due to a different cultivation method.
Green asparagus spears grow high above the ground and are discoloured by the sun to green. Green asparagus is very thin, aromatic, but also expressive in taste. They are also soft vegetables, so you don't have to peel them before cooking. That is why they have many valuable properties, because the most important substances are hidden under the skin. These are mainly magnesium, potassium, phosphorus and calcium. Green asparagus is very popular in the USA and France.
White asparagus, on the other hand, grows underground, where sunlight does not reach them. Therefore, they do not produce any dye. They are medium thick and have a delicate taste, rather mild. They are harder than green asparagus, so before cooking they should be carefully peeled, which unfortunately deprives me of many valuable nutrients. In Poland, white asparagus is grown, among others, in Wielkopolska.
Violet asparagus, on the other hand, grows a few centimetres above the ground. As a result, they have a thick violet stem. Purple asparagus contains more sugars and less fibre than white and green asparagus. This crop is also quite troublesome, because asparagus of this type needs to be harvested very quickly, even before the sun turns green.

How to buy and cook asparagus?
When shopping, it is important to ensure that the stems are free of stains and smooth and that the heads are compact. If juice (with a non-acid taste) flows out of the stem after breaking, it is a sign that the asparagus is fresh. Asparagus tastes best when freshly harvested. They are also quite impermanent. They can be stored in the fridge for 2 days, placed vertically in a container with a little ice water or wrapped in a damp cloth.
The lower ends of the asparagus are hard, so they are cut off with a knife or broken off. The asparagus is then cut starting from below the head, which should remain whole. The asparagus is cooked in a bundle in a vertical position (the heads must project above the water level) in a special high pot. They are put into boiling salted water with added sugar and boiled to softness. This usually takes 10-15 minutes (white asparagus cooks longer than green asparagus). Asparagus must not be boiled.
