Harvest fresh mint in the morning, preferably before the sun has time to heat up your mint leaves
Using scissors, snip off about 30 stalks, 5-6 inches long
Rinse at kitchen sink to remove all dust and any crawlies that might be hiding under the leaves
Measure 10 cups of water into a stockpot
Place freshly-washed mint stalks in the stockpot and cover with a lid
Set on stovetop under medium heat
Slowly warm the water, until temperatures are near boiling (turn heat off when you hear pre-boil rumbling or popping sounds from the bottom of the pot)
Remove from heat before your water boils and leave the pot's lid in place
Let sit for 10-12 minutes undisturbed
Using a large metal spoon, lift out soggy mint leaves and compost
While your tea is still quite warm, measure out honey (or your sweetener of choice) and stir in, making the concentrate sweeter than you would a mint tea drink
Pour your honey mint tea concentrate into containers and freeze until solid
Pop frozen mint concentrate blocks out of their forms and freeze in airtight bags or containers
Label and return to freezer
To use, combine 1 part mint cube/s with 2 parts water, letting the cube/s mostly dissolve before serving
