Begin by preparing a baking sheet. Line it with parchment paper for easy removal later.
Melt the dark chocolate in a microwave-safe bowl in 30-second intervals, stirring in between until smooth. Be careful not to overheat.
Pour the melted dark chocolate onto the lined baking sheet. Use a spatula to spread it into an even layer, about 1/4 inch thick.
Melt the white chocolate in another bowl using the same method. Once melted, drizzle it over the dark chocolate layer. Use a toothpick or a skewer to swirl the two chocolates together for a marbled effect.
Immediately sprinkle the freeze-dried strawberries and chopped nuts over the melted chocolate layer, pressing them in lightly to ensure they stick.
Finish with a light sprinkling of sea salt on top for a touch of contrast.
Refrigerate the bark for about 1 hour or until fully set.
Once set, break the bark into irregular pieces.
Notes
Arrange the bark pieces on a decorative platter and serve with fresh strawberries on the side for a beautiful and inviting display.
