butter candle

(名詞/可數) 奶油蠟燭 - 用奶油做成或雕刻而成的蠟燭,點亮後奶油會變軟或融化,而燭芯也是可食用的。

Late last year, we saw the first spark of interest for butter candles, but as we've moved into the holiday season, interest has heated back up again. Why not try one for your holiday table? A butter candle is literally a candle sculpted out of butter instead of wax. Just set it out with a big hunk of crusty bread and light the edible wick.
