Hi Cheffi,
The Trivita 3 ply pans from Le Creusset that we got are a 3 layer sandwich of 18/10 stainless steel with a cast aluminium internal layer, not just a base but side walls as well, so they heat up fairly quickly, dont suffer with hotspots and thus dont need to be used on high heat settings. They are also suitable for any type of heat, including use on an Aga, so when we win the lotto and move to the big house in the country I can take them with us!

They are also oven safe, so can go straight into an oven at any heat setting up to 200c
I have to agree that the cast aluminium pans do heat up amazingly quickly, and the other bonus for me is that they arent quite as heavy as the cast iron / enamelled ones that they are more well known for.
Hi Pottypotter, I love the cast iron / enamelled Le Creusset pans, had always wanted a set of the volcanic orange, but their weight was just a little too much for me when it came down to it. A couple of my friends have them and love them, but I know that in the future I would suffer with their weight, which is what ultimately put me off! Fortunately their Trivita range seems to be just what we wanted (we did look at everything else we could in a large number of shops first tho!)
