Line a baking sheet with waxed paper
Place the chocolate, cream, and salt in a large microwave-safe bowl. Microwave on high in 30-second intervals, stirring in between, until melted.
Place the chocolate mixture in the refrigerator and chill until firm, at least 1 hour 30 minutes and up to 2 days.
Roll the chocolate mixture into small balls (about 1 teaspoon each) and place on the lined baking sheet. Press one chocolate chip, pointed-side down, into the top of each ball.
Dip the tip of a toothpick in the food coloring to draw veins around the chocolate chip.
