2. Place the 3 potatoes and water in a pot, add sugar, and bring to a boil. After boiling for 10-15 minutes, check for doneness by inserting a bamboo skewer; it should slide through easily. [This is the key!] Boiling from cold water prevents the potatoes from falling apart. Adding sugar makes them moist.

3. Cut the cucumber in half and slice thinly. Place in a bowl, sprinkle lightly with salt, and let sit for a while to draw out moisture.

4. Slice the onion thinly. Place in a bowl, sprinkle lightly with salt, and let sit for a while to draw out moisture. [This is the key!] Slicing thinly and salting removes the pungency, making it more delicious.

6. Place the boiled potatoes in a bowl and mash them roughly with a fork or similar utensil. [This is the key!] Don't mash them completely; leaving some texture provides a better mouthfeel.

8. Add 3 tbsp mayonnaise, 2 tsp sugar, and the cut ham to the bowl with the potatoes and vegetables.

9. Taste and adjust mayonnaise or salt if needed.

10. Add 20g sesame dressing and 3g mustard, and mix well until uniform. [This is the key!] The sesame dressing adds richness and umami, while the mustard provides a great accent, creating a deep flavor profile that pairs well with beer. It's also delicious without mustard for children.
