Peel the banana and measure the other ingredients

Pour a small amount of sugar and water into the pan and start boiling over low heat to prevent the weak sugar from burning, do not stir, and when the sugar is completely melted, hold the pan and turn it around and melt the sugar completely.

When sugar melts and becomes syrup

Don't grind the bananas too finely in a blender, but grind them so that they have a moderate grain.

Put it in the syrup and boil it.

Add chocolate and boil it together.

Add lemon juice when chocolate has melted and mixed well with banana. Even if you don't take out the foam, it all disappears later.

Wait, let's boil it down for about 7 to 8 minutes. Bananas and chocolate mix well to make thick jam without blowing off a lot of moisture, and the banana scent is alive. Fruit jam loses its unique aroma and taste if it is boiled down for too long unless it is dehydrated.

You have to sterilize the bottle cleanly and put it in a hot state to close the lid so that it can be kept in a vacuum for a long time. When closing the lid, wipe the entrance clean with a wet cloth. The lid won't open well because it gets sticky. In that case, you can shower the lid with hot water.

You can toast the bread and eat it.
