Line a baking sheet or tray with foil or parchment paper.
In the top of a double boiler set over hot water melt the chocolate, stirring often.
Add 2 tbsp. of the cream, liqueur, and the butter and heat the mixture, stirring until smooth. If the mixture is still too thick, add the other tbsp. of cream.
The strawberries are ready to be covered. Holding each strawberry by the stem, dip it into the chocolate mixture, coating to just below the stem and letting the excess drip back into the pan.
As the strawberries are coated, transfer them to the baking sheet. Let the chocolate cool, and then cool the strawberries for 15 to 20 minutes or until the chocolate is set.
