Instruct you a few court how to master duration
Duration, it is dish cooking process in, uses firepower measurement and time length. When cook, want to differentiate the size of firepower from combustion intensity on one hand, want to hold the accident of mature time according to raw material property on the other hand. Both and unified, ability makes dish cook up to mark. Popularly says, firepower applies size to want to decide according to raw material property, but also not be absolutely. Some dish should use two kinds according to cook requirement or firepower of two kinds of above, if beef of boiled in clear soup is first flourishing fire, hind small fire; And quick-boil fish dried meat is first small fire, hind medium baking temperature; Dry carbonado is first flourishing fire, again medium baking temperature, small baked wheaten cake is made after.
Be applied in cook and hold good duration to want to pay attention to the relation of the following element.
1. The relation of duration and raw material
Dish raw material is varied, have old, have tender, have hard, have soft, the duration in cook is applied should decide according to raw material quality of a material. Soft, tender, fragile raw material is multi-purpose flourishing fire is crash, the raw material of old, hard, pliable but strong is multi-purpose small fire is long cook. But the character that if be before cook,changed raw material through preliminary treatment and characteristic, so duration is applied also want a change. Like raw material dissect, walk along water of oil, scald to wait to be able to shorten cook time. How many of raw material amount, also concern with duration size. The amount is less, firepower is about relatively abate, time is about to shorten. Raw material appearance and duration are applied also have immediate concern, popularly says, the raw material of plastic chunk is in cook, because be heated area is small, need to just can mature for long, so firepower has shoulded not be flourishing. And the raw material of broken small appearance because area of its be heated is large, urgent fire is crash can mature.
2. Duration concerns with what conduct pattern
In cook, firepower is conducted is the payoff that makes cook raw material produces qualitative change. Conducting pattern is with radiation, conduct, convection conducts heat 3 kinds means undertakes. Conduct heat agency is divided again conduct heat without agency and agency conducts heat, if water, oily, steam, salt, arenaceous bead conducts heat,wait. These conduct heat differently means is affecting what cook medium baking temperature awaits to apply directly.
3. The relation of duration and cook ability law
Cook ability law and duration are applied closely related. Fry, explode, the ability law such as boil, blast is multi-purpose flourishing fire is crash. Burn, stew, boil, the ability law such as stew is multi-purpose small fire is long cook. But the requirement according to dish, law of ability of every kinds of cook is in applying also is not invariable on duration. It is only in cook integrated all sorts of elements, ability applies good duration correctly.
The applied example that 3 kinds of duration cite below tries to explain.
(L) the dish of small fire cook
Be like beef of boiled in clear soup, boil with small baked wheaten cake. Before cooking, cut beef into square first piece, use scald of flourishing boiling water, cleared blood foam and impurity. At this moment the fiber of beef is contractive phase, should move medium baking temperature, join deputy makings, burn the moment that boil, move again on small fire, boil through small baked wheaten cake, the fiber that makes beef contractive gradually extend. When beef fast ripe when, put condiment to stew again boil to ripe, make the beef of boiled in clear soup that come so, beautiful of all of lubricious fragrance form. If use flourishing baked wheaten cake to boil, beef can appear the appearance is not neat phenomenon. There still can be a lot of beef broken bitses in food boiling water additionally, cause broth cloudy, and form watch look familiar to rot easily, still chew inside do not move. Because of the dish of this chunk raw material, multi-purpose small fire.
(2) medium baking temperature applies to scamper to make food
Always outside the raw material that hangs paste, when blast of boiler issueing oil, much use medium baking temperature leaves boiler, the method that cheers gradually, the effect is better. When be being made because of scamper if use flourishing internal heat, raw material is met instantly scorch, the Jiaolisheng outside forming. If use small internal heat, the conference after the boiler below raw material appears to paper a phenomenon. Some dish are like crisp fried chicken, it is boiler issues raw material when taking flourishing internal heat, scamper gives a stronger case, blast of again immigrant medium baking temperature comes crisp.
(3) flourishing fire is applied to explode, fry, the dish of rinse
Use the cooked food of flourishing fire cook commonly, advocate material is much with fragile, tender give priority to, if green explodes,hotpot, instant-boiled mutton, water explodes abdomen. Water explodes abdomen, when scald water, must boil goes out into boil, the ability that such rinse come out will be fragile tender. The reason depends on the dish of flourishing fire cook, can make advocate makings is rapid suffer high temperature, fiber contracts quickly, make the water inside the flesh divides not easy soak, when eating fragile tender. If not be the fire that use flourishing, firepower is insufficient, boil of the water in boiler not, advocate makings cannot contract in time, with respect to meeting general advocate makings boil old. Explode like green again hotpot, look very simple, but some people make the green that come explode the flesh, not be an a lot of soup, namely to often chew do not move. It how do ability cook is good to how do ability cook? It is to cut the flesh to want to had been cut above all, should use method carrying a knife on the head the flesh slice, must use flourishing internal heat next, oil should burn heat. On fire of flourishing of the buy that fry pan, next oil are burned to risk lampblack, again servent flesh is fried to become angry, issue green and condiment instantly stew fries moment, see green becomes angry give boiler instantly. Also be to want flourishing to be become at top speed, can cause water to be mixed more otherwise chew do not move.
But general now family expenses lights gas cooking stove, can give small, medium, conflagration only, the requirement of fire of short of flourishing. Want to use medium, small fire to fry the cooked food that fire giving flourishing cooks, above all the oily quantity inside boiler should be increased appropriately, it is to heat next time should grow a bit a bit, the raw material that puts in once again wants less, can achieve better result so.
