Water repellent-like residue on pot when cooking vegetables
I get a greasy residue in the water used to wash broccoli before cooking and in the blanching water before I freeze it. It literally only happens with broccoli so I make sure to wash it as many times as possible before freezing so it shouldn’t have any residue left when I want to cook it. I can only think that it is some sort of pesticide or preservative which is slightly worrying as I don’t want chemicals on my food! Organic is so expensive in comparison though.
