Cooking Steps

  1. 1

    Slice the cucumber into thin strips (julienne) and the tomato into thin slices or crescent shapes. Remove the pit from the umeboshi and chop it with a knife. Slice the green onion into small rounds, and prepare the grated ginger.

    Advice: Cutting vegetables just before serving allows you to enjoy their crispier texture. Soaking them in water to make them extra crisp is also recommended.

    Ingredients
    Cucumber 1/2stalk
    Tomato 1/2piece
    Umeboshi 2pieces
    Green onion 1/4stalk
    Grated ginger 4g
  2. 2

    Bring plenty of water to a boil in a pot, then carefully add the eggs. Boil for 6 minutes and 30 seconds over medium heat, then immediately transfer to cold water and peel.

    Advice: Cooling the boiled eggs immediately in cold water makes them easier to peel and stops the yolk from cooking further, resulting in a perfect soft-boiled consistency.

    In a small bowl, combine mentsuyu (2x concentrate) and water (for mentsuyu dilution) and mix well to create the dipping sauce. Chilling it in the refrigerator makes it even more delicious.

    Advice: Always dilute mentsuyu according to the instructions on the package. If you don't have time to chill it, you can add a few ice cubes.

    Ingredients
    Mentsuyu (2x concentrate) 100ml
    Water (for mentsuyu dilution) 100ml

    Bring plenty of water to a boil in another pot, then add the udon (dried noodles). Cook according to package directions, then drain using a colander.

    Advice: Dried udon noodles tend to boil over, so be careful with the heat and gently stir occasionally to prevent them from sticking. Always check the cooking time on the package.

    Ingredients
    Udon (dried noodles) 400g
  5. 5

    Rinse the boiled udon noodles under cold water, removing any sliminess, and chill thoroughly. Drain well and arrange in a serving bowl.

    Advice: Rinsing thoroughly with cold water strengthens the udon's chewiness (koshi) and makes it more delicious. Be careful not to dilute the dipping sauce by not draining the noodles well enough.

    Advice: You can also add tempura bits (tenkasu) or shichimi togarashi (Japanese seven-spice blend) to your liking. Enjoy experimenting with various toppings.
