Remove the outer loose leaves from the white cabbage and cut the stalk side off straight so that the cabbage stands better. Wrap the cabbage in aluminium foil and place on a plate. Wash the grapes, pluck them from the stalks and dab dry.
Wash the tomatoes and dab them dry. Drain the olives, silver onions, corn onions, cucumbers, cocktail cherries and mandarin chunks. Cut the cucumbers into thick slices, halve the corn onions. Wash parsley, dab dry and pluck finely.
Cut the cheese into 60-70 cubes and put them on the skewers, alternating with the other ingredients as desired. Prick the skewers into the white cabbage (possibly prick holes with a shish kebab skewer).
Keep cheese urchins in a cool place until serving.
