In a medium sized bowl, whisk together the flour, baking soda, cardamom (if using), cream of tartar and salt. Set aside.
Cream the sugars, butter and orange or lemon zest in the bowl of an electric mixer until light and fluffy (2–3 minutes).
Scrape down the sides of the bowl then add the egg and mix until incorporated. Add the vanilla extract and orange juice and beat until combined.
With the mixer on low speed, slowly add the dry ingredients and mix until just combined. Stir in the chopped strawberries.
Drop cookies by 2 tablespoons of dough onto a baking sheet lined with parchment paper. Space them 2″ apart.
Bake 13-15 minutes til tops are set and edges are golden brown. Do not overbake. Let cool on the baking sheet for 10 minutes before then transferring them to a rack to cool completely.
Notes
Strawberries: I recommend fresh strawberries for this recipe. I have not made this recipe using frozen strawberries. Cardamom (optional): Feel free to leave out the cardamom or add cinnamon instead. Orange or lemon: Use either orange or lemon. Chocolate chips: Use dark, milk, or semisweet chocolate chips in place of white chocolate chips. Chopped chocolate can also be used. Storage: Store these strawberry and white chocolate chip cookies in an airtight container in the refrigerator for up to 6 days. Freeze baked cookies in a freezer storage bag for up to 3 months. Freeze the unbaked cookie dough ballsin a freezer safe bag for up to 1 month.
