Preparation:

• Heat the clarified butter in a deep, wide pan with a lid and fry the chicken skin-side down until golden brown. Do not use too much butter, as the chicken skin often releases a lot of fat. 
• Remove the chicken and set aside.
• Add the onion to the pan and cook it gently in the remaining fat until golden brown.
• Have the hot stock to hand on the stove.
• Next add the paprika to the pan with the onion. Before you do this, check that there is enough fat in the pan to properly absorb the paprika. Add a little more butter if necessary. 
• Briefly roast the paprika, stirring constantly. Do not let it get too hot, otherwise it will become bitter. 
• Quickly add the marjoram and lemon zest, then pour in the hot stock. 
• Return the chicken to the pan. The liquid should just cover the chicken pieces. If necessary, add more water.
• Bring to the boil, put the lid on and let the chicken simmer on a low heat for about 30 minutes. It is ready when the meat easily falls away from the bone. Add salt to taste. 
• Next make the ghmachtl – the name Austrians have for a smooth mixture of sour cream and flour that is stirred into the sauce at the end. Simply mix the sour cream with the flour in a separate bowl. Use a whisk and mix until completely smooth so that there are no lumps of flour left.
• Remove the chicken pieces from the sauce. Ladle a little of the hot sauce into the bowl with the gmachtl and whisk again. 
• Then whisk the gmachtl mixture into the sauce in the pan. Bring the sauce to simmering point.
• If you like a smooth sauce, you can blend it with a hand blender at this stage. When the sauce has the desired consistency, return the chicken to the pan. 
• Leave the chicken to rest in the sauce for about 1 hour to absorb the flavours in the sauce. Gently reheat before serving.

Tip:

The dish is also excellent made with rabbit instead of chicken.
