Peel apples and kiwis and cut them into small pieces
The smaller the size, the easier it is to boil down^^

Place the cut fruit in a saucepan, add sugar and oligosaccharide, then simmer over medium heat
If you heat it too high, the sugar might get dehydrated, so be careful

When you boil it, sugar melts and moisture escapes from the fruit, creating a lot of soup. From this point on, you have to boil it slowly with patience. Remove the foam that forms here

When the fruit is ripe and soften, mash lightly with a potato mashing tool that looks like this.
If you don't have these tools, use a goblin bat to grind them slightly. If you like the texture of the fruit, grind it a little bit, right?

When the soup starts to boil down, simmer it over very low heat until it boils down. Don't leave your seat and keep stirring so that it doesn't burn~~

When it's all boiled down, put it in a hot sterilized bottle and refrigerate it~~^^
