You can always thin it with warm water when you serve it (just a tablespoon or so).

By temperature syrup runs from 218-219 degrees (assuming sea level). Even at those temperatures syrup may jell if there's a high level of natural pectin.

A syrup can also be made using a small amount of modified food starch, namely Clear Jel. Cooking would require less time and you can have it as thin or as thisk as you like and even reduce the sugar if desired.

Why not use the recipe for syrups?
I use this all the time with great results.
Syrups made from blackberries, huckleberries, raspberries, boysenberries, loganberries, sour cherries, and Island Belle grapes as well as mixtures of berries are of good flavor, color, and consistency (thin like maple syrup, medium thick like corn syrup, or slightly jelled). Syrups can be made with or without pectin and lemon juice. Lemon juice may improve color. Use of pectin will vary consistency.

To Prepare Fruit Puree:
Sort, stem, and wash ripe fruit or thaw frozen unsweetened fruit; crush fruit thoroughly; measure crushed fruit. Add 1 cup boiling water to each 4 cups crushed fruit and bring to a boil. Reduce heat and simmer to soften--about 5 for soft fruits...about 10 minutes for firm fruits like cherries and grapes. Press through sieve.

SYRUPS MADE WITH PUREE
4 cups puree
4 cups sugar
1/2 package or less powdered pectin (if desired)
3 or 4 Tbsp lemon juice (if desired)

1. Mix puree, sugar, pectin and lemon juice.
2. Bring to boil and stir for 2 minutes (boil till jelly thermometer reaches 218F).
3. Remove from heat, skim off foam, and pour into 1/2 pint or 1 pint jars to within 1/2 inch of top.
4. Adjust lids and process in boiling water bath canner for 10 minutes.
5. Remove from canner and cool.
6. Check lids, label, and store in cool, dry place.

To Prepare Fruit Juice:
Sort, stem and wash ripe fruit or thaw frozen, unsweetened fruit; crush fruit thoroughly. Place crushed fruit in dampened jelly bag and drain. For clearest juice, do not press bag to extract juice. For firm fruits, heat is needed to start flow of juice. Add about 1/2 cup water to each 3 cups crushed fruit. Bring to a boil, reduce heat and simmer 10 minutes. Place hot fruit in dampened jelly bag; drain.

SYRUPS MADE WITH JUICE
4 cups juice
4 cups sugar
1/4 cup lemon juice (if desired)
1/2 package or less powdered pectin (if desired)

1. Mix juice, sugar, lemon juice and pectin.
2. Bring to boil and boil 2 minutes.
3. Remove from heat, skim off foam, and pour into 1/2 pint or 1 pint canning jars to within 1/2 inch of top.
4. Adjust lids and process in boiling water bath canner for 10 minutes.
5. Remove from canner and let cool.
6. Check lids, labels, and store in cool, dry place.

Thanks for sharing this recipe, Linda. It's already in my database.

Thanks for the replies.

Nearly every syrup I'vemade with puree has been very very thick when I opened it. I'm just going to plan on that the next batch I make and stop thickening while it's still runny. The apple-cinnamon syrup from the Ball made with juice, is a challenge to get thick enough, however!
