Mint Jelly... Mmmm... What a treat! You could use either spearmint or peppermint. I prefer spearmint in this recipe.
Here's the recipe:
4 Cups Spearmint Tea
1/4 Cup Fresh Lime Juice
4 Cups Sugar
1 Package 1.75 ounce Powdered Fruit Pectin
Zest from 1 Lime
Green Food Coloring if you want Green Jelly
This is the color of Spearmint Tea. If you don't add food coloring, the jelly will be an amber color, similar to apple jelly.
Pour the Spearmint Tea and lime juice into a 6 or 8 quart heavy pot. Add pectin and stir until dissolved. Place over high heat and bring to a boil. Stir frequently to keep from scorching. Stir in sugar and return to a boil. Let boil hard for one minute, stirring constantly. Remove from heat. Add zest from lime stirring well. Ladle jelly into hot, sterilized canning jars, leaving about 1/4 inch headspace. (Make sure you do not spill hot jelly on your left thumb. I'm just saying...) Carefully wipe jar rims, put on lids finger tight. Process filled jars in boiling water for 5 minutes. Remove jars from hot water, cool on wire racks until set. Makes about 6 half pints.
