This recipe is great for parents to make with their children over summer vacation. If you have an electric water kettle then you don't even have to use the stove! Pudding made using hot liquid is dangerous for children but this recipe is safe and you can use regular cocoa instead of black cocoa if you want!
Put the black cocoa and salt in a bowl and dissolve them in hot water.
Put the milk, condensed milk, and sugar in a heat resistant bowl and heat it in the microwave (be careful not to let it boil!). Then add the gelatin.
Stir in 1/3 to 1/2 of the milk mixture to the cocoa mixture from step 2.
Once the two mixtures have cooled down, put them in the refrigerator and leave them to chill until they are very thick. Then take them out and whip them each up with a whisk.
If your mixtures have gotten too hard, try putting the hardened mixture bowl into a larger bowl of hot water to melt.
Use a spoon to fill your pudding molds with chunks of the cocoa mixture and milk mixture. It looks nice if you make sure not to let the same color overlap too much.
Now put the pudding back in the refrigerator to harden and it's all done. It keeps its shape better if you let it chill well.
Here is a picture of the pudding made with regular cocoa powder.
As another example, here's a mosaic pudding I made using matcha.
Story Behind this Recipe
I wanted to make a snack that was fun to make with my child.
I used a small mold in the pictures, but when cooking with children try using a bigger bowl. If the pudding has gotten too hard at step 5, the two colors won't stick together very well, so put the bowls in bigger bowls of hot water to loosen the pudding! Children will have the most fun with steps 5 and 7, so let them do it themselves.
