The other components of the cabbage family (broccoli, cauliflower, cabbage berzam, Chinese cabbage, kale, etc.) can be eaten raw. If you feel thy present too much flavor or odor, they can be bleached. This is to say, they must be introduced for a couple of minutes in boiling water.

Some, such as artichokes and cardoons, can be eaten raw, they are too bitter and it’s best cooking.
Spinach can be eaten raw but not abuse because they contain much oxalic acid.
Borage can be eaten raw, once the leaves have good brushing to remove the hairs. If they are not tender enough, it is best to eat them boiled.

What to take into account when cooking vegetables
One should take into account these tips:
– Use, unless they are in poor condition, the outer leaves are greener than those with more vitamins and chlorophyll. If they are black spots faded or present diseases, disposal.
– Wash them just before cooking. Do not use hot water. Washed with tap water at room temperature.
– Put them into the container when the water is boiling. If poured cold water, vegetables turn black due to oxidation.
– If it is green leafy vegetables, do not cover the pan so as not to spoil the vitamins that are very sensitive to high heat and chlorophyll. In the event that these have a white color, as ocurrre with thistles, the pot will be covered.
– Do not cook for too long, because in doing so break down vitamins and flavor is lost. In addition, overcooked vegetables are very flabby. To maintain the hardness of the vegetables should be added a little salt to the cooking water, except when people cook for which it is not convenient to use sodium as people with fluid retention, kidney problems or hypertension. (See cooking time for vegetables)
– Once cooked, remove them from heat and cool with tap water to remove salt and the heat does not continue spoiling the vitamins
