Potato Croquette with cheese チーズ入りポテトコロッケ

This is a form of leftovers control and I made it from my wife's mashed potatoes, which we had with roasted pork loin.  My wife's mashed potatoes were made from white potatoes (eyes removed and skin left on) cooked in the microwave oven until soft, then mashed rather coarsely, This time she added cream cheese with onion and chives spread, and buttermilk  (the buttermilk was Harrisburg Dairies whole milk buttermilk. It is her favorite and she refers to this as "high octane" buttermilk because, according to her, it is so rich and flavorful). She then seasoned it with salt and pepper. I noticed she made a lot of potatoes; much more than we needed for the meal. I commented on the large quantity. She confessed she made enough so there might be leftovers that could be used for other dishes such as my croquettes (hint, hint). A few days later, I obliged and transformed the smashed taters into potato croquettes. As seen below, I formed them into a shape like my creamy crab croquette instead of the more usual oval disk shape.

I served it with Indian-style carrot salad, and blanched broccoli.

The reason, I made these potato croquettes into this form was is to conceal a button of cheese I hid inside (I used smoked Gruyere cheese) which nicely melted.

Again, there is no recipe for this. I first made buttons of Gruyere cheese (about 5x1x1cm, or whatever size depending on how the croquette would be formed). I took my wife's leftover mashed potatoes (cold from the refrigerator and easy to form) and wrapped the cheese with the potatoes and shaped in to short cylinder form or "tawara" shape 俵 in Japanese culinary parlance. I then dredged in flour, egg wash and panko bread crumbs. I deep fried in 350F oil for 4-5 minutes turning several times.

This is best eaten piping hot with the molten cheese oozing out like the picture above. My wife was delighted with the hidden cheese surprise. For intentional-leftover control, this was not too bad.
