Heat sugar in a pan on medium heat. Do not stir the sugar and let it melt on its own.
The sugar will melt and then turn golden in color. As soon as the sugar caramelizes add the toasted hazelnuts and mix so that the nuts are completely coated with the caramelized sugar.
Pour the mixture on parchment paper and let it cool down.
After 20-30 minutes, pulse the nuts using a food processor. You can grind it fine or coarse.
Make the chocolate cups
Melt the candy melts/melting wafers according to instructions on the package.
Take 6 cupcake liners and place them in the muffin tray. The aluminium lined cupcake liners work better here as they are sturdier.
Add 1-2 teaspoon of melted chocolate in the center of 1 liner and then using a brush coat the sides of the liner with the chocolate, moving all the way to the top.
Repeat with remaining 5 liners. Once done, pop the tray into the refrigerator for 10-15 minutes or till the chocolate is firm.
Take out the set chocolate cups from the refrigerator and paint the sides of the cup again with melted chocolate. This is just to make the edges thicker.
Once done, place the tray into the refrigerator for 10-15 minutes again.
When the chocolate is set, peel the liner carefully to get the chocolate cup.
Place them in the refrigerator till ready to use.
Make the filling
Place the steel bowl of your stand mixer [or your hand mixer] and wire whisk attachment in the refrigerator for 15-30 minutes. Once the bowl is chilled, add heavy cream to it.
Start beating the heavy cream using the whisk attachment at medium speed. Add raspberry jam, vanilla extract and granulated sugar.
Beat at high speed till cream form stiff peaks [which means the cream stands on it's own when you hold it upright]. The filling is now ready.
Fill the chocolate cups
Take out the prepared chocolate cups from the refrigerator.
Fill the cups with the prepared whipped cream filling. You can either fill the cups using a spoon or use a star tip to make it look prettier.
Sprinkle crushed hazelnut praline on top.
Place 1 strawberry and an orange slice on top of each cup before serving.
Keep the chocolate cups refrigerated till ready to serve.
