Use good-quality white chocolate and melt over low heat to prevent scorching. Soak very sweet dried cranberries in warm water for 10 minutes and drain before use to reduce sweetness. Roughly chop pistachios for texture. Line pan with parchment paper for easy removal. Chill fudge fully for best texture. Variations include swapping cranberries for cherries or raisins, adding orange zest, mixing in white or dark chocolate chunks, using different nuts, adding spices like cardamom or cinnamon, drizzling dark chocolate, or incorporating shredded coconut. Store leftovers in an airtight container in the refrigerator for up to two weeks or freeze for up to three months.
