Prepare the soufflé. Place the butter in a mixer bowl. Whip for a few minutes until fluffy. Then gradually add the condensed milk to the butter, continuing to whip. Transfer the finished cream to a bowl. And pour the egg whites and a little citric acid into the mixer bowl. Start whipping and simultaneously prepare the syrup.
Prepare the syrup. Place agar-agar in a thick-bottomed saucepan, add water and place on the fire. Stir constantly while adding sugar. After boiling, add a couple of drops of lemon juice to the syrup. Combine the syrup and whipped egg whites, continuing to whip the latter. After that, combine the finished mass with the cream. Pour the resulting mixture into the desired form. Put it in the refrigerator for 120 minutes to stabilize.
Prepare the chocolate glaze. Melt the chocolate in a double boiler or microwave, combine it with the butter and stir.
Make candies. Cut the soufflé into portions. Dip each candy into chocolate glaze. Then put the finished "bird's milk" in the refrigerator for 60 minutes.
