Mint Jelly ... er Syrup

My attempt at mint jelly is more like mint syrup. Eh, all the better for mixing into drinks like mojitos or mugs of tea, right?

Mint Jelly
4 cups water
2 cups packed mint leaves
1 package powdered pectin
5 cups sugar

Combine water and mint in large saucepan. Bring to a boil, remove from heat, cover and let stand 10 minutes. Strain out mint leaves, reserving water. Combine 2 2/3 cups of water with the pectin. Return to a rolling boil, and add sugar. Bring to a rolling boil for one minute, stirring constantly. 

Remove from heat. Skim foam. Pack jelly into hot sterilized jars leaving 1/4-inch headspace. Boil in a hot water bath 15 minutes.
