Healthy cooking methods
The best way to keep the food's nutritional value is simmering, it is by far the healthiest way of cooking.
Simmering is the gentlest way to cook vegetables, poultry and fish, because it is cooked over the water rather than within them (which keeps the maximum nutritional value).
Simmering is also a relatively dietetic cooking method, since no additional fat goes into the cooking process - and there is no overheating of the oil, which can turn out to be very unhealthy. This way the food maintains and even intensifies its natural taste , as well as the color, shape and texture.
There are many ways of simmering. Many gadgets were invented to make your cooking experience easier and much more enjoyable. The best way is still one of the oldest, steaming with bamboo:
Bamboo evaporation
The "bamboo steamer" is my favorite. I purchased it many years ago. It was created in the Far East (Caution: There are two kinds. With crisscrossed strips of bamboo strips and another with bamboo strips. You'll want only the second type. It has greater durability).
The bamboo steamer is a cheap and simple tool which gives off a lovely wooden scent. You can get a bamboo steamer vessels of various sizes. I recommend 26 cm in diameter (about 10 inches), which is the most useful. The smaller vessels are designed for Dim Sam so they are less useful.
To use a bamboo steamer: put it in a wok with boiling water (make sure it doesn't touch the bottom level of the tool, so the water does not cover the food when boiled).
No wok? Place the device over a pot with the same diameter (so the device will be placed on the pot and not in it) with 5-6 cm of water. Cover, bring it to a boil and steam over medium to low heat - never on a high flame.
To add flavor to steamed food, you can steam it on a bed of herbs, green onions, sliced lemon and garlic, spinach or chard, or to prevent infection - lettuce leaves.
