Var'Hama candles were ceremonial Klingon candles. The making of the candles was an intensely laborious process involving the capture of three targs from the Hamar Mountains on Qo'noS. The targs were sacrificed at dawn and the shoulders of the animals were boiled into tallow and then hand-molded for two days to create the candles.
The tremendous amount of work and ritual involved in crafting the candles imbued them with great significance, and displaying the candles for a guest was considered an honor. Var'Hama candles were often displayed by a bride-to-be to welcome the female head of her betrothed's house prior to the wedding. (DS9: "You Are Cordially Invited"; DIS: "Battle at the Binary Stars")
