If our dishes don't need the roe to stay in its full shape (than roe omelette or roe congee, etc.), then tear the outer layer of the film and remove the intestines completely, then put the rest of the roe in a bowl and rinse it with water a few times to wash away any blood left on the roe.
The next rinsed fish roe into the water, add the appropriate amount of rice vinegar and stir after soaking for about 20 minutes, and then finally soak the roe of the water decanting on the line, so that we get a relatively clean fish roe, draining the water can be rest assured that the production of dishes.
The more demanding friends can also fry the roe again, is the roe cold oil in the pan, open the fire slowly fry the roe, and in the process of frying with a spatula to the roe into small pieces, and flatten it, and then used to make dishes after frying. Frying the roe makes it tastier, with a firm, chewy texture and a less fishy flavor.
But there are some dishes that require the roe to remain intact (such as braised roe), so we can't use the above method to clean and process the roe. In this case, we can carefully clean the fish intestines on top of the roe, keeping the outer layer of film. However, you should be careful when cleaning the fish intestines, not to pull hard, otherwise you will pull all the fish roe rotten, and can not cook.
The next step is to clean out the fish intestine of the fish roe in a small pot, filled with water, and then the small pot to the tap below, open a small stream of water slowly rinse, so that the small pot of water to maintain a slow flow of the state, so that for a period of time, the roe rinsed clean, but also take away a lot of fishy flavor.
In order to further remove the fish roe's fishy flavor, we also need to blanch the fish roe with water. Fish roe blanching should be cold water in the pot, so that the blood and dirt in the fish roe fully overflow, but also in the pot to add the appropriate amount of green onion, ginger and a high degree of white wine, these three things have a good deodorization effect.
After turning on the heat to boil the pot, you will find that the seemingly clean roe can still cook out so much froth, which indicates that the previous treatment is still not thorough enough. After all the froth is knocked out, then continue to cook on medium heat for about 3 minutes, then you can fish out the fish roe, drain the water and you can use it to cook.
