Preheat oven to 350 F. In a medium bowl, combine flour, S&P, and the leaves of four thyme sprigs.
Stir until well blended. Roll pork pieces in flour mixture until completely covered, gently shake off excess flour, and remove to a dry plate. Pierce the meat onto skewers evenly.
You should fit 3 -4 meat cubes on each stick. Rub the bottom of an enameled cast iron pot or pan with the cut side of the clove of garlic. Then reserve garlic for later use.
Heat 1/4 cup olive oil over medium high heat. When the oil is hot but not smoking, add the pork skewers to the oil and allow to brown until golden and crispy on all four sides, about 4 minutes per side.
Add a little more oil to the pan if it all gets soaked up early. Leave the pork in the pan and pour in the chicken stock and drop in two sprigs of thyme and the reserved garlic. Bring to a simmer and transfer pan to the oven, uncovered.
Let simmer for one half hour, turn skewers over and continue cooking for another half hour. Remove pan to stove top. If the juices are still thin, let simmer on stove top until reduced to desired consistency. Now you can serve this.
