Super simple, nearly free lighting. I bought these little juice glasses at a thrift store. The larger one is from an old wax candle that was used up.
Like all candles in a jar, they are self drowning. Not a big deal, it just means I need to keep another jar handy to pour off the liquid.
Today should be the last day in the oven for the beef fat. Most of the cracklings have stiffened up already, and I've started feeding them to the dogs and birds. I have 4 quarts of tallow, plus the candles, and I expect I'll get one more quart by the end of the day.
