If you want the top of your Borodinsky to shine like new shoes, grease it with a special jelly before baking. It is easy to cook jelly: into a saucepan pour 200 ml water and 1 tsp potato starch, bring to boil and cook a little more, stirring constantly. A couple of minutes and the jelly is ready. And the main advice: by all means, be patient. Rye bread must not be cut or eaten hot! It reveals its taste only after some time. It is advisable to let the bread stand for 8-12 hours.
