First, finely chop the boiled potatoes. This will be the first main layer of the salad.
Put in a mold, grease with mayonnaise and salt. You need to use a little mayonnaise, because the vegetables turn out juicy.
Next - three radishes and an onion.
Lay out the second layer, brush with mayonnaise and a little salt.
Mix the egg with mayonnaise and apply the next layer.
Sprinkle with grated carrots.
Decorate to taste and you can serve it to the table.
