There are 3 ingredients you should not wash before cooking, the more you wash, the more bacteria you get. They are as follows:
#Mushroom – Never wash or soak mushroom in the water because it can absorb water quickly. The best way to clean mushrooms is to wipe it with a damp paper towel before cooking. Otherwise, the taste will change and become flabby.
#Meat – When you wash meat, bacteria will spread, but you can eliminate bacteria by using high temperature. The best way to prevent bacteria is by patting the meat beforehand with a paper towel and do not forget to wash your hand.
#Poultry – Bacteria in poultry is a danger to your health as poultry contains a bacteria named Salmonella, which causes Gastrointestinal tract diseases and Inflammatory diseases.
Somehow, directly cooking by using high temperature is the only truly effective way to get rid of any bacteria but you are better to cook twice, like boiling poultry 2 times while replacing the boiling water to get rid of bacteria.
