a bottle of fish

A good friend of mine gave me a present - a pewter made flask with an embossed fish (believed to be a trout). Pewter is a metal alloy consisting mostly tin with small amount of copper, antimony, bismuth and lead. Yes, some of those German steins are made of pewter. Its melting point is around 200 deg C and it has excellent heat transfer capability. I look forward to taking his gift to my next trip to fish. And I am certain that it won't be fish oil based gravy for which I am using this bottle.
