Special equipment: a fondue pot, optional
Bring the half-and-half to a simmer in a fondue pot or small saucepan. Add the chocolate and stir until completely melted. Stir in the raspberry liqueur and vanilla.
If using a fondue pot, place in on the fondue burner. Otherwise, simply bring the saucepan to the table (the chocolate will remain at a dipping consistency for over an hour).
Serve with an assortment of dippers such as strawberries, bananas, pound cake, angel food cake, brownie bites and coconut macaroons.
