I just noticed that my Le Creuset enamel cast iron dutch oven has multiple pinprick holes in the enamel. They bubble when I heat up oil in it. Is this normal or a defect?
I received this as a gift over a year ago.
Today, while heating up olive oil in it, I saw that there are multiple pinprick holes that bubble rapidly once the oil got hot.
I have also noticed the smell of onions when boiling water in it previously, despite not having put any onions in the water. Is it possible that food is getting caught in the holes?
