Wet a piece of kitchen paper towel and place it at the bottom of the rice cooker. Put the eggs on top and turn on the power. Once the power switches off, leave the lid closed for another 10 minutes to finish the boiled eggs.

Remove the cooked eggs and place them in ice water to cool.

Wash and dry the cucumber, then dice it. Add a little salt and mix to remove the raw taste.

Peel the eggs and mash them with a masher.

Add mayonnaise and sweetened condensed milk.

Mix well, then add salt and black pepper.

Drain the water from the cucumber and add it to the mixture.

Mix well, and it's done!
