Peeling the pineapple

Peeling the mango

Preparing the melon
Remove the kernels of the melon with a spoon. Use a knife to peel off the outer shell. Peel the kiwi with the peeler. Peel the bananas.
Cutting fruit
Cut all the fruits into small pieces on a porcelain- or glass plate.
Do not use a board or otherwise the fruit may take on any other odors.
Mixing with gelling sugar
Weigh the fruit pieces and place them in a plastic or glass bowl. The value 2: 1 means that one portion of sugar supplies two parts of fruit. So one kilogram of fruit = a pack of sugar. If the fruit weighs less, simply weigh the amount of gelling sugar in the adjusted ratio. Mix the fruit with the gelling sugar, the lemon juice,the citric acid and let it drain for at least half an hour.
The citric acid supports the pectin contained in the gelling sugar and let's jam jell better.
Cooking in the microwave
Bring the mixture to boil in the microwave at the highest level. Leave it boiling for five to seven minutes. Open it again and again and stir well.
Filling in into twist-off glasses
Fill the jam as long as it's hot into prepared, sterilized twist-off glasses and seal them with their lid. Put the glasses upside down.
When the glasses cool down, a vacuum will be established in the glass. Thus, the glasses are sealed tightly and the jam is durable for several months.
