To start with we will need some fresh kiwifruit, apple and lemon together with caster sugar. There are a few types of kiwifruit available from the fruit stalls or supermarket depending of which countries they are from. I am sure you have tried the green kiwifruit and golden kiwifruit which is yellowish after removing the outer skin.
You might like to take this photo as reference to shows the steps and changes that took place while cooking the jam.Ingredients: (make about 1 cup)
2 Medium Size Green Kiwifruit, about 150g
1 Apple, about 150g
220g Sugar
Rind of 1 Lemon
Juice of Half Lemon
Method:
1. Bring a pot of water with jam bottle in it to a boil and boil them for 5 - 8 minutes or so to sterilize them, removed and invert for them to dry.
2. Peel off the skin from the kiwifruit and apple and chopped them into fine cubes.
3. Place all the above ingredients in a heavy-duty saucepan(choose a slightly higher saucepan as the mixture will rise as it boils) and bring to boil over medium high heat and stirring occasionally.
4. Reduce heat to medium and cook, stirring constantly and skimming foam as necessary.
5. Cook about 10 minutes, until mixture begins to look syrupy and thickens slightly.
6. Once the mixture is stiff enough with a glossy outlook remove the pot from the heat and start filling the jam bottle.
7. Fill the jam near to the rim, screw the cap on and leave it to cool.
8. The jam needs to be refrigerated to prevent mold from forming and it can be kept in the fridge for 2 - 3 weeks.
Note:
1. The jam will look rather watery when done, but don't worry it will thicken up when it cools down to room temperature.
Kiwifruit consists of twice as much vitamin C as there are in oranges so in fact you need one kiwifruit each day to get that amount to replenish your daily intake. But if you or your kids don't prefer to eat the fruit as it's own, perhaps you can consider to some kiwifuits to make some smoothie or jam like what I have shared above.
