To fix the taste of salty red caviar possible in 20 minutes. Put the product into a deep bowl and add warm water. See that eggs are not cooked, the water temperature should not exceed 25-30 degrees, otherwise the eggs just turn white. You need to soak about 7 minutes, stirring lightly. In a colander place cheesecloth and place the eggs to drain. After 10-15 minutes I can already taste the salted eggs.
If red caviar is a little precise, but not permanently, but only got a light acidity and slightly perceptible unpleasant odor, fill it with regular tea brewing. Then you can rinse also with water, but this is optional. Put the eggs to drain excess fluid.
Milk will save quite missing the eggs, though, taste is not the one that fresh. Pour the eggs boiled cold milk and allow to soak for 30-60 minutes. This method is suitable in extreme cases, but there is no guarantee that you will not poison.
Spoiled fish products, you can not just poison, but even to get treatment in the hospital. Be careful, you should ditch the caviar, if it is clearly flawed.
Black caviar "resuscitated" in a similar way.
