Select high-quality chocolate (dark, milk, or white) based on your flavor preference.

Using a double boiler, gently melt the chocolate, stirring continuously to avoid burning.

Optional: Temper the chocolate to achieve a glossy finish and crisp texture.

Fold in roasted, unsalted pistachios and optional ingredients such as sea salt or vanilla extract.

Pour the chocolate and pistachio mixture into a chocolate bar mold or a lined baking dish.

Optional: Garnish with additional chopped pistachios or a sprinkle of sea salt for added texture and flavor.

Allow the chocolate to set at room temperature or in the refrigerator until firm.

Once set, break or cut into bars and enjoy your luxurious pistachio filled chocolate bars.
