I would like to purchase a 30cm Mauviel fry pan and lid, however they don't seem to be sold together. I found the fry pan on e.dehillerin's website, and I'm searching for a lid to match, but have read they don't always fit snugly when purchased separately. Can anyone advise what size lid would I need to purchase for the 30cm Mauviel fry pan (2.5mm copper/stainless steel interior)? Any suggestions where can I find this lid? (I've searched the e.dehillerin website, but cannot find a matching 30cm copper lid.) Thanks in advance for any help!
