Please juice the lemon. Lemon keeps the fruit's natural color because it prevents it from discoloring.

Slice the banana thinly, please. It browns well, so please cut it quickly.

Place bananas in a bowl, add lemon juice and mix.

Bring bananas and 1/3 cup bottled water to a boil over high heat.

Boil for about 10 minutes. Even if you don't mash it separately, it becomes lumpy after 10 minutes.

Add sugar, bring to a boil over medium heat, then bring to a boil over low heat. When you add sugar and start boiling, it bubbles a lot..Please remove the foam. From this point on, let it boil over low heat for 10 minutes.

If you boil it for 10 minutes after adding sugar, it becomes lumpy like this. If you want the ingredients to be there, you can just do it. Mash slightly with a spoon if you want to do it without. Add one important piece of sugar, take half of the jam, and place it in another bowl. Or you can make it at the same time. Half of it is to make chocolate jam.

Banana jam is finally done. I made a jam with a little lump.

You can use it when you don't know if the jam is good or if you put it in a bottle. If it doesn't spread when you scoop a little jam and put it in cold water, you can put it in a jar of jam.

It's a banana with sugar in it. It's slightly crushed with a spoon.

Add dark chocolate to the banana. I put in the thinly ground dark chocolate. Add together and simmer for another 10 minutes.

It doesn't taste as chewy as strawberry jam, but I think it tastes better than strawberry jam.

bottles disinfected in boiling water. It's good to make it in a small bottle and eat it's good to eat it often. I put it in like this and eat it for about a week.

The color is really pretty and the taste is as good as the pretty color. Banana jam. Banana chocolate jam is done.
