Jack-o-lantern

 is a Cooking craftable item.

Note: Look carefully when buying the candle, Sean sells two types. Buy the 'roundish' candle holder as opposed to the one that appears to be sitting in a cup.

Note: It is also possible to loot a candle which will work; look for the 'roundish' bottom candles.
