Servings: 80servings, 5 to 6 half pint (8 oz) jars
2 to 4cupsfresh lilac blossomspetals only, no stems or green parts
4cupswater
4 to 5whole blueberries or blackberriesoptional, for color
For the Jelly:
4cupslilac teastrained
1/4cupbottled lemon juiceor 1 tsp citric acid
1boxPowdered Pectinregular, such as Sure-Jell (1.75 ounce box or 6 Tbsp if bulk)
5cupsgranulated sugar
Instructions
Pluck the lilac petals from the clusters, leaving behind all stems and green parts, which are bitter. Place the petals in a heatproof jar or bowl.
Pour the boiling water over the petals so they're fully submerged. For color, muddle in a few blueberries or blackberries. Cover and steep 15 to 20 minutes.
Strain the tea through a fine mesh sieve or cheesecloth to remove the petals and berries. Measure, adding water if needed to reach the full amount.
Pour the tea into a large pot and stir in the lemon juice. Bring to a boil over medium-high heat.
Whisk in the pectin until fully dissolved and boil hard 1 minute. Don't add the sugar yet, or the jelly won't set.
Add all the sugar at once and stir to dissolve. Return to a full rolling boil and boil hard exactly 1 minute. Remove from heat and skim off foam.
Ladle hot jelly into prepared jars, leaving 1/4 inch headspace. Wipe rims, center lids, apply bands fingertip-tight.
Process in a boiling water bath 10 minutes, adjusting for altitude. Rest 5 minutes with the heat off, then cool undisturbed 24 hours before checking seals.
Notes
Important Note ~ Lilac flavor varies a lot from plant to plant, so before a full batch, steep a small cup of tea, stir in a little sugar, let it cool, and taste it. Most lilacs make a lovely jelly, but the occasional bush just isn't good, and a quick taste up front saves a batch you won't enjoy.Adding Color ~ Lilacs don't release much color into the tea, so the jelly is pale on its own and can fade toward gold after canning. Muddle a few blueberries or blackberries into the steeping water for a soft purple that holds up, without changing the flavor.Yield ~ This recipe makes 5 to 6 half-pint jars (about 3 cups of finished jelly).Doubling ~ Don't double this recipe. Pectin jelly sets on a precise balance of liquid, sugar, and pectin, and a doubled pot often refuses to gel. Make two single batches back-to-back instead.Give It Time to Set ~ Pectin jelly can take 24 to 48 hours to firm up. If it's still loose after that, hold off on re-cooking and check the troubleshooting guide first.Altitude Adjustment ~ Process for 10 minutes at elevations below 6,000 feet, or 15 minutes above 6,000 feet.Low Sugar Option ~ For a lighter jelly, use Sure-Jell Low Sugar or Pomona's Universal Pectin and follow the mint jelly directions on the package. With Pomona's, raise the lemon juice to 1/2 cup, since it has no added citric acid in the powder. Less sugar also means a smaller yield.A note on lemon juice ~ The lemon juice is required for safe water bath canning, not just flavor. Use the full 1/4 cup of bottled lemon juice and don't cut it back or swap in fresh. It's also what turns the turquoise tea pink.Make the Tea Ahead ~ Steep the lilac tea and refrigerate it a day or two, or freeze the strained tea for several months, before turning it into jelly.
