Dice the onions, chop the garlic and fry both with the bacon for about 5 minutes over medium heat (but be careful, garlic turns black quickly and tastes bitter. Better to add later). When everything is golden brown and smells good, pour in the sweet cream and add the crème fraîche. Cut the mild peppers into slices and add. (The peppers give the sauce the right whistle.)
Cook the noodles in the chicken stock until firm to the bite, then drain and mix with the cream, bacon and pepper mixture.
You probably won`t need salt at the table because the bacon is salty, more like pepper.
