Instruction
1. Sponge cake
Preheat the oven at 170 Celsius degree in 10 minutes
Separate egg yolks and egg whites
Beat 4 egg yolks with 20 gr grnulated sugar
Pour cooking oil, milk and vanilla extract into beaten egg yolk, mix well
Mix all purpose flour with corn starch, then sieve and mix flour mixture into egg yolk bowl
Don’t overmix the mixture, you should only mix the flour until it disappeared
In another bowl, beat egg white with ½ tsp lime juice (or cream of tartar) and sugar until stiff peak.
Add ½ beaten egg white into egg yolk bowl, stir quickly until they’re combined
Pour the mixture back to meringue bowl, use a spatula to mix them together with “fold method”
Divide cake batter into 2 equal parts in 2 separated clean bowl. Mix 1 part with 2-3 drops of red coloring.
Transfer cake batter into piping bag
Pipe cake batter on baking tray that lined parchment paper as videos (or as the way that you prefer)
Place baking tray in oven and bake at 170 Celsius degree in 25-30 minutes
Remove baking tray from oven, use a knife to spit the cake from edges
Sieve a thin layer of powdered sugar, place a parchment paper on top and then a cutting board. Flip it up
Take baking tray away, remove baked paper. Place another layer of parchment paper on its surface and cover it by a baking tray, then flip it up again
Roll the cake when it’s still warm and let it cool on tray
This step will help sponge cake from cracking when you roll later with whipped cream filling
2. Strawberry cream filling
Whisk 150 ml whipping cream with sugar until stiff peak
Add and mix 40-50 gr strawberry jam into whipped cream.
You can save up 20-30 gr of strawberry whipped cream for decorating later. And here is recipe of homemade Strawberry Jam
Wrap it up and refrigerate for 20-30 minutes before using
3. Cake assembly
Cut fresh strawberries in small cubes
Spread sponge cake on plastic wrap
Transfer cold whipped cream on cake surface and sprinkle with strawberries
Roll the cake up and refrigerate in 30-60 minutes to set cake roll
4. Decorating
Remove roll cake from plastic wrap
Trim 2 side of roll cake for better look
Pipe strawberry whipped cream on top, decorate with fresh strawberries and mint leaves
Store in fridge and serve within 1-2 days
⚠️ ATTENTION!
Sponge cake should be rolled when it’s still warm to keep its shape, so that when you roll with whipped cream the cake won’t be cracked or split out
Whipped cream should be kept cold through process to prevent it from melting (that will be absorbed into sponge cake). Cold whipped cream is also easier to spread on cake surface and roll up
