Queen Anne's Lace Jelly

Place two and a half cups of firmly packed flowers in four and a half cups of boiling water. Allow to steep, covered, for half an hour. Strain the liquid. ( It will be green and smell like a new pair of sneakers.)
Pour the strained tea into a pot. Add one box of pectin and 4 TBS of lemon juice. Bring to a full, roiling boil, then stir in three and a half cups of sugar. Return to a full boil for about 5 minutes. Pour in sterilized jars and seal.

After reading numerous recipes online for this, I learned it's common to add 2 boxes of pectin, or boil longer than 5 minutes, because it has a tendency to remain syrupy. It also changes from green to pale pink/peach after adding the sugar, and the odd smell disappears. It may take 24 hours to set.
