It looks like 5ml. Our traditional household porcelain spoon is 15ml. When eating boiled fish, put a bowl of boiling water in front of you, hold it and let the fillets float in the water. In fact, there will still be some oil on the fish, and the taste will not be too bad. I tried. After the meal, there was a thick layer of oil floating in the bowl of water. It makes me happy to think that I haven't finished eating so much oil.
