Cut the grapes in half or quarters, depending on their size. Slice the celery thinly and dice the apples into small cubes, leaving the peel on. Roughly chop the walnut kernels.
400 g grapes, 4 stalks celery, 2 apples, 100 g walnut kernels
Mix sour cream, honey, lemon juice, salt, and pepper together. Whip the cream until it forms soft peaks; it shouldn't be too stiff, just lightly whipped. Fold the whipped cream into the dressing. Use a spatula to gently combine them to avoid deflating the dressing too much.
2 dl sour cream, 1 tbsp honey, 1 tbsp lemon juice, ½ tsp salt, Pepper, 1 dl whipping cream
Combine celery, apple, grapes, and walnuts with the dressing. You can reserve some walnuts for garnishing, if desired.
Arrange the salad in a bowl and garnish it optionally with walnut kernels and celery leaves.
