Trim the rind from the pork chops and "score" the fat on the top edge a little, then set them aside whilst you prepare the remaining ingredients.
Cut the shallot in half, peel it and then dice it as finely as you can.
Peel the garlic cloves and dice them as finely as you can.
Rub the pork chops with olive oil and then generously season them with the salt and pepper.
Heat a 28cm or 11" frying pan or skillet over a high heat, then sear the pork chops all over (1-2 minutes a side), making sure you pay attention to the fat! Then remove and set aside.
Reduce the heat to medium and add the butter. When it begins to foam, add the garlic, shallots and thyme and cook for a minute or two, take care not to burn these ingredients. If the pan is too hot, remove it from the heat.
Add the chicken stock and brown sugar, then stir to create a sauce.
Return the pork chops, flipping them over to get a nice coating, then transfer them to the oven and cook them for 12-15 minutes at 170°C or 340°F.
Remove the chops and let them rest, and return the pan to a medium heat. Mix the cornflour with the water, stir it into the sauce and cook for a minute or two to thicken.
I like to strain the sauce through a fine mesh sieve before serving, but that is optional.
