Preparation of Filling Savory Sponge Cake
To prepare the savory sponge cake for filling, first separate the yolks from the whites and place them in 2 separate bowls.
Then, beat the yolks with the sugar until you have a whitish and frothy mixture.
Also beat the egg whites with salt until very stiff peaks.
Now sift the flour with the baking powder and add it to the freshly beaten yolks very gently from bottom to top.
Finally, fold in the beaten egg whites in 3 batches, thoroughly incorporating them before adding more.
Preheat the oven to 340°F in static mode, and while it reaches temperature, butter and flour an 8-inch diameter springform pan.
Pour the sponge cake mixture into the cake pan and bake in the central rack of the oven.
Then bake the sponge cake for at least 40/45 minutes (do not open the oven for the first 30 minutes) and before removing, check the level of doneness with a toothpick.
It should come out dry.
Remove the sponge cake from the oven and let it cool well before removing it from the pan.
Slice it into 3 parts and then work the ricotta with a fork to make it creamy.
Chop half of the arugula together with half of the black olives and half of the capers, and mix everything with half of the processed ricotta.
Spread some ricotta on the first sponge cake slice, cover with slices of smoked salmon, and add arugula to taste.
And distribute over it a portion of ricotta mixed with olives and capers that you previously prepared.
Place the second sponge cake disk on top, applying slight pressure to adhere, then spread again with ricotta, sliced smoked salmon, arugula, and more ricotta mixed with olives and capers.
Cover with the last disk, spread the remaining ricotta on top, and decorate with the rest of the black olives cut in half and some capers.
Finish with arugula leaves and smooth the outer edges with more ricotta.
Let the Filling Sponge Cake rest in the refrigerator, tightly closed in a cake holder or an airtight container for at least 2 hours before serving.
