Begin by creaming together two sticks of salt and butter with three-quarters cup of granulated sugar and one and a quarter cup of brown sugar until well combined, being careful not to over mix.
Incorporate two room temperature eggs and a teaspoon of vanilla into the mixture.
If you choose to use it, add a quarter cup of sourdough discard and mix until the texture resembles wet sand.
Next, add one and a quarter teaspoon of salt, one and a half teaspoon of cornstarch, one and a quarter teaspoon of baking soda, and three cups of all-purpose flour all at once.
Mix the ingredients until they are almost combined, leaving a bit of flour still visible.
Fold in two cups of semi-sweet chocolate chips and mix until everything is fully combined.
Roll the dough into balls that are roughly three to four tablespoons in size (about 70 grams) and place them in the freezer.
Preheat your oven to 375 degrees and bake the cookies for 13 to 15 minutes, adjusting the time based on how crispy you prefer the edges.
