Most British sausages are made with breadcumbs or rusk or other starches like rice flour etc, so would not be induction friendly.

What ingredients are in a lorne sausage?

If you can get hold of plain sausagemeat or ground pork with nothing added you could make your own sausage patties by adding seasonings.

I sometimes make them by grinding up bellypork (which is fattier than chops or pork steak which can make for a very dry sausage).
