A resourceful submission from James Steele:

1/2 cup (volume) or 8 tablespoons 
1.5 pints or 900 ml or 3 3/4 cups of water
Sweetener or lemon (optional)

Gather the pine needles (the ones nearest the end of the branch).
You can chop up the pine needles or leave them whole.
Jetboil your water, of course it won't take long to bring it to a boil. Add the needles to the boiling water and reduce to a simmer for about 20 minutes. The longer you steep, the stronger the tea.
You can strain out the needles and enjoy. Or you can use the Coffee Press accessory and press the needles to the bottom of your Jetboil and sip from the lid.
Pine Tree Tea is good for scurvy which is a constant threat while backpacking. Plenty of vitamin C in Pine Tree Tea.
