Add a little salt to the boiling water and boil for 15 to 20 minutes.

Check while poking with chopsticks!
Tip.
If you want to shorten the time to boil potatoes, divide the potatoes into 2~4 pieces and boil them.

While potatoes are cooked, cut onions and ham and prepare them.

Pour oil into the pan and cook the onions until they are transparent

After the onions are cooked, add ham and cook together.

Crush the cooked potatoes with a whisk

Crushed potatoes with grilled onions and ham, then season with salt and pepper
Add a spoonful of mayonnaise as if it is acting as an adhesive.
And shake it, shake it!

Roll the croquette into a circle of appropriate size,
Make a hole in the middle and add cheese in moderation.
And the key is to cover the cheese well with potatoes so that it can fit in the middle of the croquette
(If you don't do it right, croquette spits cheese when you fry it...)

After making croquette,
Roll it on top of flour -> Coat it with egg water -> Roll it on bread crumbs to finish!

Fill the pan with about a fifth of the oil and cook the croquette by rolling it
If you stir it with chopsticks and turn it upside down
You can meet croquette with all the intestines sticking out

Cool the croquette on oil paper,
If you spray parsley with a point, the visual goes up by 1%.
