Preheat oven to 175°C. Grease and line a 38x25 cm jelly roll pan with parchment paper.
02 -
Cream softened butter with 2 1/2 tablespoons sugar until smooth. Incorporate 1/3 cup sifted cake flour, then add the egg white mixing until uniform. Divide paste into separate bowls and tint with desired food coloring.
03 -
Transfer colored pastes to piping bags and pipe desired pattern onto prepared parchment. Freeze the design while preparing the batter.
04 -
In a mixing bowl, whisk egg yolks with 1/4 cup granulated sugar until light and sugar is dissolved. Gradually drizzle in vegetable oil while whisking. Add milk, almond extract, salt, and optional food coloring; mix until combined.
05 -
Sift 2/3 cup cake flour over the egg yolk mixture and gently fold until fully integrated.
06 -
Beat egg whites until frothy. Add remaining 2 tablespoons sugar and continue beating to medium-stiff peaks.
07 -
Fold one-third of the whipped egg whites into the batter to lighten it, then gently fold in the remaining whites until just incorporated.
08 -
Pour the batter evenly over the frozen design in the pan. Tap the pan gently to release air bubbles and level the surface.
09 -
Bake in the preheated oven for approximately 10 minutes until the surface springs back lightly and edges are barely browned.

Invert the warm sponge onto parchment paper, carefully peel off the backing, dust with powdered sugar, and cover with a clean tea towel. Flip the cake so the design faces down.
11 -
Roll the sponge gently in the towel and allow it to cool completely for 1 hour to prevent cracking.
12 -
Soften gelatin in cold water, microwave briefly until fully dissolved, then set aside to cool slightly.
13 -
Pulse freeze-dried strawberries with 3 tablespoons sugar in a food processor until finely ground.
14 -
Beat heavy cream until frothy. Add powdered sugar and continue beating until soft peaks form. Incorporate a spoonful of whipped cream into the gelatin mixture, then fold this back into the cream.
15 -
Fold the powdered strawberry sugar mixture into the cream, beating until medium-stiff peaks are achieved.
16 -
Unroll the cooled sponge, remove the towel, and spread the strawberry cream evenly, leaving a 1.3 cm border at one edge. Roll the cake gently but firmly.
17 -
Wrap the rolled cake tightly in plastic wrap and refrigerate for a minimum of 2 hours or overnight to set.
18 -
Using a serrated knife, cut the chilled cake into 10 to 12 even slices for serving.
