Although I have already given a few recipes for spoon sweets (fruit preserves), I forgot to mention how we know if the syrup is ready. It is very important for spoon sweets and jams that the syrup has the proper density.
If we have doubts and don’t know if the syrup is ready this is what we should do.
For spoon sweets:
Place some syrup in a spoon and let it drip away in the saucepan. When all the syrup has dripped a final drop must remain hanging but not falling off the spoon.
If it does, that means that the syrup is not ready and you should repeat procedure again.
Chill a saucer in the refrigerator, put a few drops of the mixture on the small plate and try to move it around. If it starts flowing then the syrup is not ready yet. If it resists movement, then it is ready; remove from heat immediately.
Depending on the content of water in each fruit some take more time than other fruit to set.
Of course, if you have a candy thermometer, it needs to reach up to 105o C / 220o F.
Follow the instructions in each recipe as well as above method.
If you have done all the above and the syrup has not set, this means that the fruit did not have enough pectin. This can be fixed by adding powdered pectin. Bring to a boil again for 1 – 2 minutes and follow the instructions on the package. The one I use is 1 sachet (25 grams) powder for 1 kilo fruit and 500 grams sugar.
Store the jam in a cool, dry place and when opened store in the refrigerator.
Note: If the syrup of the spoon sweet is properly thickened, then all the spoon sweets can be preserved for a very long period of time without having to keep it in the refrigerator.
For other syrups, used for making liqueurs, wetting cakes, etc., after boiling point, reduce heat and simmer for 5 minutes.
Tip: Always add lemon juice in your syrup as it contains pectin and it will also prevent sugar from crystalizing.
