Please note, these treats are extremely tasty, particularly suitable for weddings but preparation takes lots of time and patience.
Total preparation time: at least 5 hours!
Chop the large dried fruits (pineapples and strawberries) very finely and put them in a suitable bowl. Grind the walnuts to flour (using a walnut grinder) or simply grate them finely and mix with the coconut flakes in a separate wide and deep plate.
Place the eggs in a Duralex or enameled container, pour on 1 cup sugar, place this container into an even larger container with water that reaches halfway up the smaller container (in other words make a water bath). Beat the eggs in the water bath with a whisk until the mixture starts falling off thickly in strips. Take the container with the cream out of the one with the water and continue beating until it cools a bit. If left to cool on its own, it'll catch a hard crust, which is not what we want!
Beat the butter to foam with the powdered sugar and vanilla. To it, add the cooled egg mixture spoon by spoon, while stirring. And so, after about an hour something, the cream is ready.
Caramelize a little sugar at the bottom of a small pot or small, deep pan. Add the milk with 3-6 tbsp sugar. Bring to a boil, stir well and leave it to cool. Then season it with the rum essence.
Soak the cake layers with this mixture right before you begin cutting circles out of them.
Using a small brandy glass (up to 1 1/4″ (3 cm) diameter) or something similar (such as a plastic cap with the same diameter), cut out circles from the cake layers and arrange them in a suitable container (such as a tray).
At this point, you have the following in front of you on the table: a tray with circles, container with cream, container with small fruits and container with walnut flour. Smear each circle with a little cream, put 3 pieces of fruits on top, then another circle, smear thus formed little cake on all sides with cream and roll it in the mixture of walnut flour and coconut flakes.
What you end up with is something like a ball. After about 3 hours, you're now filling up the wide glass plate with these balls, the so-called wedding treats in question. You should get about 70-80 of them. Put them in the fridge so that the cream can harden and then (after eating them) you're going to enjoy unparalleled ovations from your guests.
And one more thing! When cutting the cake layers into circles you're going to have material left over, which you can mix together with some of the cream, add a little cocoa and white chocolate (melted in a water bath), form balls with a dried fruit in the middle and roll them in the walnut-coconut flour too.
