For the walnut ice cream with lemon honey, whip the whipped cream until stiff, chop the walnuts and roast them briefly in a non-stick frying pan until they are fragrant, then allow to cool.
Fold sugar and walnuts into whipped cream. Freeze whipped cream mixture in a plastic container, stir 3 times at one hour intervals. Mix honey and lemon juice well.
Pour ice cream into 4 glasses with an ice cream scoop and serve each garnished with a spoonful of the honey mixture and 2 holhippen.
