For the apple compote, stir together the apple juice, lemon, mustard and honey, put in a saucepan and bring to the boil. Reduce the liquid to 1/8 l. Add the apple cubes and let simmer for 3 minutes. Salt, pepper and add half of the thyme. To let it cool down.
Quarter walnuts. Melt the sugar in a pan, froth the butter in it, add the nuts, add the remaining thyme leaves. Salt lightly and let cool.
Wash and clean salads and pluck them into bite-sized pieces.
Mix a vinaigrette from vinegar, oil and water and finally mix in the parsley.
Layer the goose breast and apple compote alternately on plates as a kind of turret, decorate with the walnut brittle next to the salad mixed with the vinaigrette.
The amount of vinaigrette is very generous, I think 2/3 of the amount is enough.
