What better way to clean a cast iron pan than by making gravy? Mmm
And whats with the talk of chipped beef......on a hunting site....)
I prefer venison, very lean of course

And vinegar on chip/fries is an English thing.
Ketchup? well Food for thought
Quote
The story of ketchup—from the fermented fish sauces of China and Southeast Asia to the sweet chutneys of England and America—is, after all, a story of globalization and of centuries of economic domination by a world superpower. But the superpower isn't America, and the century isn't ours. Think of those little plastic packets under the seat of your car as a reminder of China’s domination of the global world economy for most of the last millennium.
