There was a vast spread of cold salads which was a welcome respite on a hot, sultry summer June day. I immediately reached out for the chilled Japanese Potato Salad regally plated in a large, elegant, transparent glass bowl.

The firm, yet moist potato cubes were nestled prettily next to carrots, cucumbers, mashed hard-boiled eggs. All the salad ingredients were coated with the silky, creamy mayonnaise dressing. I scooped two servings on my plate and I knew this savory-sweet salad was all I wanted for lunch, in spite of the other inviting entrees that were on display at the buffet.

When we returned back to our home in America, I couldn’t wait to recreate the Japanese potato salad in my own kitchen. This was just the thing for the oppressive heat wave we’ve been having on the east coast this summer month. I found a good Japanese potato salad recipe from my food blogger friend Namiko Chen of Just One Cookbook. Her recipe inspired me to make the same chilled salad.


The difference between Japanese potato salad and the American version is that the Japanese one has partially mashed potatoes, crumbled hard-boiled eggs and uses the Japanese mayonnaise.

What is Japanese mayo and how different is it from the USA brands? Namiko explained it well on her blog. Following her suggestion, I purchased the Kewpie Mayonnaise, one of the most popular Japanese brands. The difference lies in the flavor of the mayo. Japanese mayonnaise is made of egg yolks versus American mayo which uses whole eggs. Also, rice vinegar is used in the Japanese mayonnaise while distilled white vinegar is found in the American versions.

I started making the potato salad early in the day to give it time to stay chilled in the refrigerator for a few hours. The richer, creamier texture of the Japanese mayonnaise was a joy to mix into the potato salad. The silky, pearl-like cream substance worked its magic on the potatoes, crumbled hard-boiled egg and other vegetable ingredients. I gently folded the ingredients to blend well. The mild, sweet aroma of the mayo mixing into the newly-boiled potato cubes was an inviting treat. I couldn’t wait to serve this Japanese potato salad to my family paired with the summer barbecues we were grilling outdoors. This salad had the right amount of sweet and salty which appeals to Filipinos and pairs well with Filipino food.

We don’t mind the heat wave really. It just gives us more excuses to enjoy the comfort of a huge bowl of  superb Japanese potato salad.
