Apples, sausage and mayonnaise play an important role here, and the taste of the salad depends on them.
If the apples are slightly sweet, then they prefer to sprinkle with lemon first, and then add to the rest of the ingredients.
But if you add a little more pickled cucumbers than indicated in the recipe, sweet and sour apples without lemon juice will be very useful.
I usually use smoked sausage.
