Steps
Finely chop the onion in the amount shown in the photo above, then pickle it with a little salt.
Once moisture comes out, squeeze it out thoroughly.
Adding raw onion directly makes the flavor too sharp, but pickling it in salt softens the pungency and brightens the potato filling, which can otherwise feel heavy and dense.
Doing it this way makes it unexpectedly great in a potato sandwich.
Peel the potatoes, rinse them in cold water, chop them roughly, and microwave for about 4 minutes.
They cook thoroughly to the center. Mash the cooked potatoes well so there are no lumps.
They mash much more easily while still hot.
Thinly slice the cucumber on a diagonal.
To the mashed potatoes, add the finely chopped imitation crab stick, minced pickled onion, along with the carrot and sweet corn, which are not in the picture but were added later.
Thinly slice and finely mince the carrot before adding, and make sure to thoroughly drain the canned sweet corn before adding.
Add all the filling seasonings listed above and mix well until everything comes together.
Spread jam on the inner side of the bread slices, then spread the filling over it.
Place the cheese on top of the filling.
Layer with the thinly sliced cucumber, then the ham. Finally, spread jam on the inside of the top bread slice and cover.
Wrap the sandwich in plastic wrap and press it down with a heavy object placed on top.
Cut neatly to your liking, either into large pieces or small bites.
Ppunwife's tips
- Adding raw onion directly makes the flavor too strong, but pickling it in salt tones down the sharp pungency and adds a refreshing note to the potato filling, which can easily feel heavy and dense.
- Cooked potatoes should be mashed while still hot so they crush easily without forming lumps.
FAQ
Why salt the onion instead of using it raw?
It reduces the sharp, pungent bite of the onion and gives a refreshing lift to the potato filling, which can otherwise become heavy and dry.
What is the easiest way to cook and mash the potatoes?
Peel and roughly chop the potatoes, then microwave them for about 4 minutes until cooked through to the center. Mashing them right away while hot makes them smooth with minimal effort.
Why wrap the sandwich in plastic wrap and press it down? AI-generated
Wrapping it tightly and pressing it with a heavy object helps the bread and fillings adhere closely together, keeping the layers from falling apart when sliced.
