Use good-quality chocolate for the best flavor and texture. Make sure not to overbake the pie; the center should be slightly jiggly to keep it creamy. Press the crust firmly into the pan to prevent crumbling when slicing. Allow the pie to chill fully for clean, neat slices. For a nut-free version, omit the nuts or substitute with chocolate chips or dried fruit. Use pasteurized eggs or egg substitutes if you prefer to avoid raw eggs in the filling. Variations include adding nuts, marshmallows, coffee, peanut butter, or making vegan versions. Store leftovers covered in the refrigerator for up to 4 days or freeze, but add fresh whipped cream after thawing.
