PREPARE THE VEGETABLES

Wash and peel the carrot.

PRO TIP: You might only need to use 2 or 3 inches of the carrot for the recipe but keep the carrot whole to make slicing easier and safer.

PRO TIP: Taste your cucumber and decide how much skin you need to peel.

For Japanese style cucumber cuts, peel small, spaced out strips.
If your cucumber skin is tough to chew, just peel the entire cucumber.

Salt the carrot and cucumber with 1 tsp of salt, mixing them gently to distribute the salt, and leave them in a colander or drainable container for 10/15 minutes.

COOK THE POTATOES
🥔

Person slicing potatoes on a cutting board in a kitchen.

Peel and chop the potatoes into rough cubes and put into a pot with COLD salted water.

PRO TIP: If the water doesn’t taste salty, add more salt. Think ocean water salty.

Boiling eggs in water in a pot on an electric stovetop.

Bring the potatoes to a boil. Only once the pans starts boiling, set a timer for 10 minutes.

PRO TIP: This cold-to-boiling method allows the potatoes to cook evenly. If you boil the water first and then put the potatoes in, the outside of the potato cooks faster than the inside, resulting in an uneven texture.

After 10 minutes, poke a potato with a knife or chopstick to see if it is soft enough. You might need 2-4 more minutes.

Once the potatoes are soft enough to mash, drain the water, and put the potatoes back into the same pot with a lid.
Give them a nice shaky-shake, and remove the lid to help the extra moisture and steam escape.

Add the vinegar while the potatoes are still hot! Start with 1 tsp, mix, and then taste. I used 1 tbsp, but add up to 2 tbsp of Japanese vinegar.

WARNING: MIXING MAYO INTO HOT, VINEGAR POTATOES CAN CURDLE!

BOIL & MASH THE EGGS
🥚

Two eggs inside a stainless steel cooking pot on a wooden countertop, with a red egg thermometer label inside the pot.

Add 1-2 eggs to a pot of cold water with a lid. Bring to a boil, and without removing the lid, turn off the heat. Set at 12 minute timer.

PRO TIP: Cooking the eggs using this method keeps the yoke from becoming chalky and dry, and the white being rubbery.

When the timer goes off, put the eggs into a jug of ice water, the colder the better! This stops the cooking process and can help peeling.

PREP HAM, CORN, & VEG

TIPS & TRICKS

Additional toppings

Once you’ve created your potato salad, adding dry toppings such as dried fried onions or sprinkles of katsuobushi (dried bonito tuna) can add a nice extra crunch and smoky hit to the dish.

Keep it consistent

Try not to over mayo your potato salad, the consistency should be creamy enough that all the ingredients can hold together on a spoon, but not so drenched in mayo that it tastes too rich and wet.

Serving it Up:

You can make your potato salad the day before you plan to eat it, just make sure to taste it, and add an extra squeeze of mayo before serving if the salad consistency seems dry.
