Like many of you, I spend Saturday morning
thinking about obscure kitchen tools that
I don't already have. Like these two:

http://cgi.ebay.com/ws/eBayISAPI.dll...m=220201592569

Anyone have a clue as to how they work?
Are they missing any pieces? Why would
anybody boil milk?

So, to educate myself, I looked around
for other examples, but that only added
to the mystery:

Whoa! A completely different design!
At least, one of them has instructions.
Apparently, these sit in the bottom of
a pot of milk, spiral side down. Steam
bubbles presumably travel along the
spiral groove before exiting through the
hole. What's the purpose of doing that?

The instructions say it prevents boiling
over, but wouldn't the real problem in
boiling milk be scalding? Is preventing
boiling over the only purpose accomplished
by this tool?

The name of the latter unit, "Milk Saver",
implies that this is done to preserve milk,
maybe an early form of pasteurization?

I suspect the spiral design funnels the steam bubbles up into a
narrow stream so that you don't have bubbles coming up from every
part of the bottom of the pan, which is what causes the foaming
and boil over.

Neat design.

But I have no clue as to why you'd boil milk other than for
puddings, pasteurization, and some bread making applications -
which usually don't require a extended heat or large quantities.

It may be used to re-pasteurize milk that has started to "grow".
Same theory id used in the "Chinese master sauce": As long as
heat it frequently, it won't go bad.

Much of the western world drinks very milky coffee for breakfast. Lots of
recipes ask for boiled milk. Certain hot chocolate recipes require boiled
milk. Hot milk is thought of as a cure for insomnia or nervous conditions.
The question is not why but how best to do it. Ergo these inventions.

Because milk is a good vector of lots of diseases, including TB.
Boiling it prevents them. Today we buy pasteurized milk in much of
the world, but that's fairly recent.
