01 - Line a baking sheet with parchment paper, ensuring complete coverage.
02 - Gently melt the semi-sweet chocolate using a double boiler method or in 30-second intervals in a microwave, stirring after each interval until completely smooth and fluid.
03 - Pour the melted semi-sweet chocolate onto the prepared baking sheet and spread it evenly into a layer approximately 0.5 cm (¼ inch) thick.
04 - Immediately distribute the broken mini pretzels and chopped dried cherries evenly over the melted chocolate. Use a spatula to gently press the mix-ins into the chocolate base.
05 - If using white chocolate for decoration, melt it and drizzle it artfully over the bark.
06 - Sprinkle uniformly with flaked sea salt, if desired, for an enhanced salty contrast.
07 - Transfer the baking sheet to the refrigerator and chill for a minimum of 30 minutes, or until the bark is completely firm and set.
08 - Once solidified, break the bark into irregular pieces. Store in an airtight container at room temperature for up to one week.
