Make the ladyfingers. In a large bowl, beat the egg whites until thick and soft peaks form. Add the sugar in two or three parts and continue beating to make a stiff meringue.

Add the egg yolks and stir until evenly mixed.

Sift the cake flour and quickly fold it in.

Put a sheet of paper the size of the circumference of the cake pan under the parchment paper to act as a guide for squeezing the batter to the correct height and length of the ladyfingers.

Put the batter in a pastry bag with a 1.5 cm tip and squeeze it out. You will use the leftovers, so make extra.

On a separate baking sheet, squeeze out a 16 cm diameter circle of batter to use for the base. Smooth the surface.

Sprinkle only the lady fingers to be used for the sides generously with powdered sugar so that the surface is white. Bake all of the parts for 12-13 minutes. (All at once, or in batches.) Leave on the parchment paper to cool.

Return to heat and cook until slightly thickened, stirring constantly with a wooden spatula. (Do not use a whisk.) The foam should disappear, and it should be bubbling lightly from the bottom. Remove from heat, add the softened gelatin and stir to dissolve. When the mixture has cooled slightly, stir in the liqueur.

Line a cake pan with a removable bottom with parchment paper, with the paper slightly peeking out above the top of the pan. Place the baked ladyfingers made in Step 8 tightly together around the sides of the pan, leaving no gaps. Put the cake base on the bottom. Brush the inside with canned pear syrup.

The leftover ladyfingers will be used in the bavarois, so cut about a ladleful into cubes and coat them with 1~2 tablespoons of pear syrup.

Go back to making the bavarois. Place the pot in Step 10 in cold water and stir until slightly thickened.

Whip the cream over ice water until soft peaks form. Stir in the mixture from Step 13.

Assemble: Pour half of the bavarois in the prepared cake pan. Next, put in the cut up ladyfingers and diced pears. Pour in the remaining bavarois. Smooth the top and chill in the fridge for about an hour.

When the bavarois is almost set, start the decoration.

Arrange thinly sliced pears on top and brush the top with warm nappage. (If you don't have any, you can top it with a jelly made with gelatin leaves, water, and sugar that has been chilled over ice water to spreading consistency.) Decorate with berries rolled in nappage.

Chill in the fridge for 3~4 hours until firmly set. This shows what it looks like when cut. To serve, dip a knife in hot water, wipe the knife clean, and cut, using a slow sawing motion. Repeat this for each slice.
