I cooked a splendid goose for Christmas lunch. V nice it was. And we ended up with a load of goose fat in the bottom of the roasting tray, as geese are fat old birds. Brilliant I thought, a year's supply of goose fat, potato roasting for the use of, so I decanted it into various tins and jars.
Except it won't solidify, even after I put it in the fridge. I'm guessing I've got some kind of impurities in there, but how to get rid of them?
