I am surprised that the solution of a big candle and a small Bic hasn't even been raised.
I mentioned that above, just not the same words.
Aha! Yes you did. Missed that.
I haven't used a big candle-in-a-can, though I have used a tealight with some extra wicking like TP jammed down into the wax. Anything with a long-burning, insistent flame makes the job easier. I generally just carry a candle stub from those long-burning Ikea candles. And in various pockets, there will be a few Coghlans fire sticks (they don't get messy on you).
Around here, a few extra sticks and bark bits have generally been enough to shield the fledgling fire. I haven't had to make fires in the midst of the relentless monsoons seen in coastal areas.
