Query: rusty

Beware. Forget about ordering a metal pudding mold unless it's stainless steel. I bought these for my 2011 Plum puddings and when I unpacked them for my 2012 pudding they are rusty and the rust is very smelly and can't be washed out. I threw them away and will stick to stainless or porcelain bowls.
