Line a baking sheet with foil or waxed paper.
In the top of a double boiler set over hot water melt the chocolate, stirring. Add the 3 tablespoons of cream and the butter and stir until smooth. Holding each strawberry by the stem, dip into the chocolate mixture allowing the excess chocolate to drip back into the pan. If necessary, add additional cream to the chocolate to achieve desired coating consistency. Transfer the coated strawberry to the lined sheet and repeat process. Allow the chocolate to cool and then chill the strawberries until chocolate is set, about 20 to 30 minutes.
