I would say grab a bag of carbonation drops and add them to the bottle for simplicity of one bottle. Just my opinion.
I have sugar and honey but I do not have carbonation drops. I prefer to use what I have to not have to run to the store every time I am out of an ingredient.
3/4tsp of white sugar works
One Domino Dot sugar cube will give you about 2.4 volumes of CO2. You could use this carbonation calculator for one bottle.

Handy piece of information to know. I couldn't tell you the last time I saw a sugar cube, but the grocery store is a lot closer than the brew shop.
Just weighed one level teaspoon of regular table sugar at 4.0grams, I believe a good amount to carbonate a 12oz beer.
1tsp is often too much, in my experience. 1/2-3/4tsp is perfect.
Oh crap, you're absolutely right! I was thinking 22oz, not 12.
Let's see, I use 5oz sugar for 30x 22oz bottles, that would be 4.7 grams per 22oz bottle, or 2.6 per 12oz, at that rate. So yes 1/2-3/4tsp = 2 to 3 grams.
