Preheat the oven to 350 F. In a medium bowl, whisk together flour, salt, and baking soda. In a large bowl, combine butter with sugar until fluffy. Add in egg and lemon juice until smooth.
Add in the flour mixture, mix until it is fully combined. In a shallow dish, combine granulated sugar and ground cinnamon. Roll the cookie dough into balls, then roll into the cinnamon sugar mixture.
Place the cookies onto a large ungreased baking sheet at least 2-inches apart. Bake for 10-12 minutes.
