Begin by preparing your pineapples. If you're using canned pineapple, drain them thoroughly and squeeze out any excess water or juice using your hands. This ensures that you don't end up with a watery jam.
If you're opting for fresh pineapples, remove the skin, cut the fruit into chunks, and blend them in a blender for about 10 seconds. You want the pineapple to be mushy but not completely liquefied.
Transfer the blended pineapple into a deep, preferably non-stick pan. This will help prevent sticking and burning during the cooking process.
Add in the measured sugar and cloves. Stir well to combine all the ingredients. You'll notice how the sugar begins to dissolve and mix with the pineapple.
Now it's time to cook! Put the pan over medium to low heat. Allow the mixture to simmer gently. You want to keep an eye on it to ensure it doesn't stick to the bottom of the pan.
As the jam cooks, you'll see most of the liquid evaporate, and the jam will start to thicken. This is where the magic happens! Stir constantly to avoid burning the bottom. Keep the mixture moving for the best results.
Once the pineapple jam has turned a beautiful golden color and reaches your desired thickness, it's time to taste. If you feel it needs more sweetness, add a little more sugar at this point and stir.
Remove the pan from the heat and carefully take out the cloves if you added them. Let the mixture cool down for a few minutes.
When the jam has cooled slightly, transfer it into sterilized jars. This is important to ensure the jam stays fresh. Place the jars in the fridge to let it cool completely and set. You can enjoy your Pineapple Jam once it’s chilled!
