In a medium-large bowl, place 2 to 4 cups of spruce tips.
Pour 4 cups of boiling water over the spruce tips, allowing the water to become infused with the flavor of the spruce tips for 15 minutes.
Pour the spruce tip-infused tea through a cheesecloth or strainer into a medium saucepan or jam pot. Discard the spruce tips.
Prepare your jars or containers for jelly, pre-measure the sugar you need, and set the sugar aside for now.
Add 2 Tablespoons of lime juice to the spruce tip tea.
Over high heat, bring the mixture to a boil.
While stirring, slowly add the pectin.
Return the mixture to a hard boil and allow it to boil for one minute.
Add the premeasured sugar to the mixture slowly, stirring continuously, allowing the sugar to dissolve.
Continuing to cook over high heat, bring the mixture back to a hard boil, stirring while boiling for 1-2 minutes.
Ladle or pour the jelly into prepared jelly jars or containers, leaving ¼" headspace at the top of the jar.
Wipe the rims of the jars or containers with a wet, clean cloth.
If you are going to can your jelly, put the canning lid on the jar and screw on the ring until finger-tight. Do not over-tighten. If you plan to refrigerate or freeze your jelly, place lids on the jars or containers and leave the jars to cool and set up for 24 hours.
If canning, process the jars in a water bath canner for 10 minutes (or 15 minutes if above 6,000 feet in elevation).
Unprocessed jelly should be stored in the refrigerator for up to 1 month, or in the freezer for 6 months. Canned jelly will maintain quality for up to 18 months in your pantry or cool, dry place. For all jelly, refrigerate once opened.
