Drain the boiled salsify, then cut into 1-2 cm pieces. Dice the thick slices of boiled ham and roast them lightly in hot butter. Bring the cream with a little salt and pepper and the vegetable stock to a boil in a saucepan, reduce by about 1/3, thicken with the mixed flour. Add black salsify and ham and simmer in the sauce for a few minutes.
Mix with 2 egg yolks if you like. Croquettes and a seasonal salad, for example, go well with this. Then a fruit salad, a great winter menu.
