Does your Mum keep a jar of bacon grease in the pantry ?
mine never did.
Beef dripping was sometimes used to cap off potted hough, but bacon fat? that was either used to fry stuff in or scraped out for the birds. Stinks the kitchen out
Candles are pretty cheap to buy these days, £stores and the like, leave the bairns crayons alone
Interesting to see what folks do though. TomBear has some good stuff posted on using rushes and fat to make home made lights. From both his results, and those of others who do this kind of thing, the cleanest, least smelly and least sooty candles are made from cleaned up mutton fat. It actually smells like a kind of wax rather than fat burning.
cheers,
