Preheat the oven to 350 degrees F. Line 2 large baking sheets with parchment.
Whisk together the flour, salt and baking soda in a medium bowl and set aside.
Place the butter, brown sugar and granulated sugar into a stand mixer and beat on medium-high speed until combined. Scrap down the sides and mix briefly. Add the vanilla and eggs and beat on medium-high until combined. Mix in the lemon curd, stem ginger and lemon zest.
Lower the speed to medium and slowly beat in the flour mixture in 2 batches. Fold in the white chocolate chips.
Scoop 6 heaping tablespoons of dough onto each prepared baking sheet, about 2 inches apart. Bake until golden brown, 11 to 15 minutes. Let cool on the baking sheets for 15 minutes before transferring to a rack to cool completely. Store in an airtight container for up to 3 days.
