This was another delicious celeriac recipe.
Warm half butter/half oil in a thick bottomed cook pot, and add cleaned, diced celeriac with some salt and (optional) a teaspoon sugar. Just leave on the stove cooking for as long as it takes to be done: 30 to 45 minutes.
Serve with blue cheese sauce:
Melt crumbled blue cheese (de Causses or d'Auvergne) and grated regular cheese (Cheddar, or Gouda or Gruyère, depending on your native country!) into a tablespoon of crème fraîche, until all is well mixed and one substance.
The sweetness of the celeriac and the sharpness of the blue cheese go very well together!
