25 Comments on “How To Make Mouthwatering Star Fruit Jam”
Do the fruit need to be ripe or really ripe for the jam
Hi David,
The starfruit should be yellow / orange, not green. But how ripe? As ripe as you can find them. But it will be more difficult unless you have your own tree.
Hello, I would like to know if during the 4 days that the jams rest I need to put them in the fridge. Thanks!
It definitely helps Alex. Here in Costa Rica we need to.
No where in the instructions does it say where and when to add the 3 cups of sugar! Since all the other ingredients are added and then put in the fridge to rest overnight, I will assume the sugar goes in at the same time.
i would like to make it at school
i have the tree at home how could i pick it green are ripe
That is no problem. You might need to add a little more sugar. Let us know how it goes!
This sounds easy enough and yummy. Does it just make one pint jar or do I need more? I want to sterilize the jars ahead of time.
Should these jars be refrigerated to keep them from spoiling? Do you can the jam? What keeps it from spoiling?
My suggestion is to always keep jam in the fridge, or a really really cool place. Like a pantry.
Like to know in ounces or kilos please also what size cup. Thank you
Can I waterbath the jars for longer shelf life?
I have to say I was a little impatient making this jam as I couldn’t wait for the starfruit to ripen. So I made it with a mix of ripened star fruit and some yellow and green. It was delicious. Now I have my own tree so for the next batch I will wait and try and be patient! Thank you for sharing
I have some fruit that is Stillgreen how can I make this fruit ripen faster ?
If the fruit is still green, you can use it for jam. But if you wanted to ripen it, leave it out on the counter for a day or two.
Hi BlueOsa, Is there any water required in this recipe?
“…until liquid is evaporated”
Do not add water Ingrid. You will find that star fruit has a lot of natural water in it.
Seriously! 1/8 CUP of vanilla?
It doesn’t say the serving size. Could you clarify?
Hi Zoe
You can guesstimate. What matters most is that you cook it for sometime to reduce the liquids.
Can I put the fruit in a crock pot and let it cook down like Apple sauce
Absolutely! That sounds delicious. Let us know how it goes.
Can I put fruit in crock pot and cook down like applesauce
Sure. that would work. You just want to reduce it.
