Ingredients
- 1 whole cucumber
- 1 pinch salt
- 1 cup cherry tomatoes
- 1 block ham
- 2 whole eggs
- 1 splash white dashi
- 2 tbsp sugar
- 3 tbsp rice vinegar
- 3 tbsp soy sauce
- 2 tbsp water
- 1 tbsp sesame oil
- 1 tsp chicken bouillon powder
- 2 packages Chinese-style noodles
Instructions
- 1Slice the Cucumber

Take a whole cucumber and carefully cut it into thin slices using a sharp kitchen knife on a wooden cutting board. Continue by stacking or arranging the slices to slice them into fine, uniform strips.
Tip: Keep your fingers curled inward like a claw to protect them while slicing. - 2Salt and Massage Cucumber

Transfer the shredded cucumber strips into a clean glass bowl. Sprinkle a small amount of salt evenly over the cucumber strips, then gently massage them by hand to draw out excess moisture.
Tip: Allow the salted cucumbers to sit for a few minutes before squeezing out the liquid for a crispier texture. - 3Cut Cherry Tomatoes

Place fresh cherry tomatoes on the cutting board and use a kitchen knife to cut them into small, bite-sized pieces or halves depending on preference.
Tip: Use a sharp serrated or utility knife to easily slice through tomato skin without squishing them. - 4Slice the Ham

Take a block of ham and slice it lengthwise into thin, uniform strips that match the size of the cucumber strips.
Tip: Stack the ham slices flat to cut multiple uniform strips efficiently. - 5Crack Eggs and Season

Crack two fresh eggs into a clear mixing bowl, ensuring no shell fragments fall inside. Add a splash of white dashi to enhance the savory flavor profile.
Tip: Crack eggs on a flat surface rather than the edge of the bowl to avoid pushing shell pieces into the whites. - 6Fry the Egg Omelet

Whisk the egg mixture thoroughly, then pour it evenly into a heated non-stick pan. Cook until it forms a thin, delicate sheet or omelet.
Tip: Swirl the pan immediately after pouring to spread the egg mixture into an even, thin layer. - 7Slice the Egg Omelet

Carefully slice the prepared egg omelet into thin, neat strips on a cutting board. These delicate egg ribbons will serve as a classic colorful garnish to top the cold noodles.
Tip: Let the egg omelet cool completely before slicing to prevent it from tearing or sticking to the knife. - 8Mix the Noodle Sauce

Combine sugar, vinegar, soy sauce, water, sesame oil, and chicken bouillon powder in a mixing bowl. Stir the mixture continuously until the sugar is fully dissolved and all the ingredients are well blended together.
Tip: Stir well to ensure the sugar crystals dissolve completely in the liquids before pouring over the noodles. - 9Boil the Noodles

Bring a large pot of water to a rolling boil, then add the packages of Chinese-style noodles. Cook the noodles according to the package instructions until they reach the desired tender texture.
Tip: Stir the noodles gently right after adding them to the boiling water to prevent them from clumping together. - 10Rinse the Cooked Noodles

Drain the cooked noodles in a metal strainer and rinse them thoroughly under cold running water. This cools down the noodles instantly, stops the cooking process, and removes excess surface starch for a better texture.
Tip: Rub the noodles gently under cold water to ensure they are fully cooled and thoroughly washed. - 11Assemble the Ingredients

Place the prepared cold noodles into a serving bowl. Neatly arrange the sliced cucumber, ham, egg strips, and cherry tomato halves on top of the noodles as colorful toppings.
Tip: Arrange the toppings in separate sections around the bowl for a visually appealing presentation.
