Yeah, like we all have spiders in our kichen. That was totally unexpected...

A spider is a type of skimmer used in Asian and Dutch cooking in the form of a wide shallow wire-mesh basket with a long handle, used for removing hot food from a liquid or skimming foam off when making broths. The name is derived from the wire pattern, which looks like a spider's web.

I hadn't run into the spider either - doesn't mean it isn't valid, but wow it's obscure!
