The wife's investment
I have a Le Creuset 3.5 and find that I use it way more than I thought I would. If someone already has a large and small saucepan and is wanting to add another, I’d recommend a saucier because it is so versatile.This was a fun read. I've never felt I needed a saucier but that's just personal preference in the kitchen. A good saucepan just works well for me. Also, in most cases for any given volume saucepan, I'd rather have the extra cooking surface area in the base.
Won't lie though, I've been tempted before by that 3.5 qt Demeyere saucier jbaca mentioned above, but talked myself out of it.
As an aside... for anyone out there contemplating AllClad cookware, take a serious look at Demeyere first before making a decision. You'll be glad you did.
