Thoroughly scrub the potatoes under running water, rub with butter and cook in a baking dish for 1-1.5 hours at 170 ° convection. If you stick a fork in the potato and the potato doesn`t get stuck on it, it is done.
Remove the peel from the garlic cloves, dice, place in a container brushed with oil and put in the oven for 30 minutes.
In the meantime, fry the bacon in a pan until crispy, allow to cool and break into small pieces.
Put the cooked potatoes with their skins in a saucepan and cut roughly with a fork. Now add milk (cream), garlic, salt, pepper and a little butter and beat everything to a puree. Then stir in the bacon and season with salt and pepper!
