Pork tenderloin is the pig meat equivalent of fillet steak. Provided it is cooked properly and in an appropriate fashion, unlike many other cuts of pork it will be served super tender as well as tasty. The fact that tenderloin is usually considerably less expensive to buy than fillet steak makes it an even more attractive choice for your table. While the piece of meat is normally cooked and served in steak sized portions, slicing it in to small medallions as in this instance not only means it cooks more quickly but that your purchase will go a lot further and serve many more people.

Potato is Peeled and Trimmed

Potato is peeled and trimmed at each end

The potato should be peeled as normal before being trimmed at each end that the ends are completely flat. Try to avoid trimming away too much of the potato but you do want to have a fairly large surface area on each side.

There are actually quite a number of slightly different ways in which it is possible to make fondant potatoes. Water, stock, butter and even olive oil are commonly used in the process but if there is one major problem often encountered with a number of the techniques it is that the potato chunks can remain hard to the point of being inedible in the center when they are cooked to perfection on the outside. The cooking method described here is one of the ones most likely to ensure your potatoes are cooked to perfection every time.

Start by cutting the peeled and trimmed potato across the way in to three equal width chunks. Lay these chunks in the base of a medium sized pot.

Stock and Butter added to Potatoes

Stock and butter are added to pot with potato

Slowly pour the chicken stock in to the pot until the potato pieces are just covered and quite literally no more. Add the butter and put the pot on a medium to high heat until the butter is melted in to the stock and the resultant liquid combination has reached a simmer.

Adjust the heat under the pot to maintain a medium strength simmer. The idea is to boil off all the stock over a period of around half an hour to leave only the melted butter for the final few minutes of cooking.

Starting to Grill Pork Medallions

Starting to grill oiled and seasoned pork medallions

When the stock level in the pot with the potatoes is starting to get fairly low (after twenty to twenty-five minutes), put a cast iron grill pan on to preheat to very high. This will take a few minutes. Put a medium pot of salted water on to come to a boil. Lightly oil the pork medallions all over using a pastry brush, season with salt and pepper and grill in the hot pan for about two minutes each side.

A ridged, cast iron grill pan such as the one used in the preparation of this recipe affords a wide range of culinary benefits, in the kitchen and even beyond. It cooks food more quickly than a standard frying pan and often in a healthier fashion as the ridges allow much of the saturated fat to drain away. It can be used on the hob, on the outdoors grill or even on a campfire and it is so sturdy, provided you care for it properly and per the manufacturer's instructions, it can easily last a lifetime. If this is not a cooking method you have tried before, you may find yourself introduced to a whole new world of exciting culinary possibilities.

Grilled pork medallions must be rested

Lift the grilled pork medallions with cooking tongs to a heated plate or flat bottomed bowl. Cover with aluminum foil and leave for a few minutes to rest. Put the tenderstem broccoli spears in to the pot of boiling water and simmer for three to four minutes. 

Stock is Evaporated leaving Butter

Stock is almost completely evaporated leaving potatoes in melted butter

It is necessary to monitor the potatoes constantly when the stock has all evaporated and you are left only with the slightly sputtering butter. Reduce the heat and cook for two or three minutes before very carefully turning the potatoes over to cook for a similar few minutes on their second sides. Drain the tenderstem broccoli through a colander at your sink and leave to steam off and dry out for a couple of minutes.

Turn the heat off under the pot containing the potatoes. Lift each fondant potato piece to a plate covered with kitchen paper and gently pat dry before lifting to the serving plate.

Slicing Chorizo

Slicing Spanish chorizo

The chorizo slices are entirely optional. I simply thought this spicy Spanish pork sausage would add both a little bit of extra color and flavor to the dish. If you are using chorizo, do make sure that you buy the pre-cooked and ready to eat type and not the type (usually of central American origin) which requires to be cooked before it can be eaten.

Lay a chorizo slice on top of each tenderloin disc. The heat will quickly cause them to melt slightly, imparting extra flavor to the pork.

Broccoli is Plated

Lay the broccoli stems on the plate, ideally using them to divide the potato and pork assemblies as shown above.
