Roast the hazelnuts in a pan without fat, take them out and let them cool down. Chop the chocolate coating and coconut oil. Heat the cream. Add couverture, coconut oil and liqueur and melt. Mix the chocolate mixture and hazelnuts, pour into a bowl and cover directly on the surface with foil.
Chill for 2-3 hours. Put the cocoa on a small tray. Whisk the mixture with the whisk of the hand mixer for about 1/2-1 minute. Leave to rest briefly (the mixture becomes firmer as it rests). Roll into approx. 25 small balls with cool hands. If the mixture is too soft, refrigerate again. Roll the chocolates in the cocoa. Place on baking paper and chill for about 2 hours. Finally, use tweezers to place the gold leaf on the pralines.
