Indulge in the decadence of homemade chocolate truffles for a luxurious Valentine's Day treat. In a saucepan, heat heavy cream until it simmers. Pour the hot cream over chopped chocolate and let it sit for a few minutes. Stir until the chocolate is completely melted and smooth. Add any desired flavorings, such as vanilla extract or liqueur. Let the mixture cool, then refrigerate until firm. Roll the chilled ganache into small balls and coat them in cocoa powder or chopped nuts. These homemade chocolate truffles are a rich and indulgent way to celebrate love.
