Boil the potatoes in water with plenty of salt (about 2 tbsp) and, if you like, a little lovage. Bring the water to the boil before adding the potatoes. Cook the potatoes for 6–8 minutes (you can prick them lightly to check) and then leave them to stand for a couple of minutes before draining the water.
Mix the smoked cheese and mayonnaise together. Dice the kohlrabi, radishes and pickled gherkin into small cubes, and mix them into the cream. Cut the potatoes into thick slices and toss them in. Season with salt and freshly ground pepper. Garnish with chives and thin slices of radish. ENJOY!
