Cut the thighs in half, wash them with cold water, season them with salt and pepper, sprinkle them with beer (half the amount) and leave them to cool for 30 minutes.
You light the fire in the oven.
When the oven is hot, season the thighs with Maggi spice and place them in the bag, in the oven tray and leave them for 45 minutes.
After this time, open the bag, sprinkle the thighs with the rest of the beer and leave for another 10 minutes, to brown nicely.
