Grate or chop chocolate into small pieces. Using a serrated knife makes the task of chopping easier.
Gently heat cream in a heavy bottomed saucepan over low heat.
Don't allow it to boil. As soon as you see tiny bubbles delveloping on the sides, take the pan off the heat.
Add grated or chopped chocolate and vanilla extract.
Mix well till the chocolate melts completely.
The mixture should appear smooth and shiny.
Pour the ganache into a shallow tray and allow it to cool down in the fridge for 30-45 minutes.
Lightly grease your hands with butter.
Scoop about a tablespoonful of the ganache and roll it into a ball using your palms.
Make a depression in the middle like a small cup.
Add about one teaspoon of the pomegranate arils.
Bring the edges together and close. Roll.
Place the rolled ganache on a lightly greased tray.
Repeat with the remaining ganache and pomegranate arils.
Let the chocolate truffles chill again for 10-15 minutes.
Roll each truffle in cocoa powder.
Store in an airtight container till required. They taste best when chilled.
