To continue with the foody theme, China has become a huge market for American poultry growers.

Not just for chickens but for their feet.

Like us, chicken producers remove the feet when they send their birds to the supermarket but some bright spark has just realised that these are a much sort-after luxury in China.

According to one statistic, the Americans exported 169,000 tons of such feet to China last year because they are a favourite snack to go with a beer.

I have tried them – once – and I shall stick with potato crisps, thank you very much. At the same time, the Chinese are also scouring the world for another tasty toothsome: pig’s trotters.

They can’t grow enough little piggies to send to market to feed their one billion people.

So do we have here a new product for the export market that the Prime Minister is so keen to promote?

In fact, when I was nobbut a lad in the days of food rationing, which extended well into the 1950s, every small town had a specialist pork butcher which specialised in items like black puddings, palony, brawn...and pig’s trotters.

We ate them from time to time, when other meats were in short supply and they were okay: virtually tasteless but filling for an active young lad.

Many years later, in my days as a restaurant critic (see above) I was offered pigs trotters in a very posh place in Harrogate.

Most of the bone had been removed and the remaining skin stiffed with jellied meat and herbs.

They were delicious. Perhaps we will be forced to go back to these traditional English foods when we can no longer afford imports. And a very good thing too!
