Nagasaki Milkshake

This regional treat is not really a milkshake. It is more like a shaved ice topped with condensed milk and egg yolk. Nagasaki Milkshakes are always eaten with a spoon. You can get them in cafes around the city.

This is a regional take on a refreshing drink that everybody knows. The original Nagasaki Milkshake (pronounced miruku se-ki) is more a dessert than a drink. It’s sort of like a shaved ice made with condensed milk and egg yolks. They have a genuine ice cream parlor taste and once you have eaten one, you may be craving another! You eat this treat with a spoon- it is too thick for a straw. One thing is for sure – Nagasaki locals love this treat. There is even a local pop group named after it!

Nagasaki Milkshake (Milk Seiki)

The good news is that a delicious milk se-ki can be made without a shaved ice machine – here is a blender friendly recipe to try. You will need a blender or a food processor that can pulverize ice to make this recipe.

5 minutes 2 servings
PREP 5 minutes
YIELD 2 servings


  • 8 TBSP (1/2 cup) 100% sweetened condensed milk
  • 2 raw egg yolks*
  • 6 TBSP (3/8 cup) cold water
  • 2 1/2 cups ice
  • 2 maraschino cherries


Add the condensed milk, egg yolk and water to a mixing bowl and whisk together until smooth. Pour the mixture into the blender. Then add the ice.

Blend until smooth and the mixture is thick and frosty. It should be too thick to pour without clumping together.

Spoon into two frosted glasses, top with a cherry.

Serve with a spoon.


Make sure that the egg, water and milk is closer to the blade and the ice is on top. This will ensure the ingredients are well combined when you run the blender.

Raw food products can carry dangerous bacteria. I suggest you use pasteurized egg that has not exceeded the published expiration date.
