In a large bowl, combine the flour, baking soda, and salt. Stir everything together well and set it aside.

In a mixer, take the softened butter and sugar. Cream them together until the mixture is fluffy and light.

To the butter-sugar mixture, add in the egg, lemon juice, lemon zest, vanilla extract, and yellow food coloring. Mix everything together until you have a smooth batter.

Gradually add the dry ingredients into the wet mixture. Stir until a sticky dough forms.

Once the dough is ready, cover it and chill it in the refrigerator for at least 2 hours.

Preheat the oven to 350°F (175°C). Prepare your baking sheets by lining them with parchment paper.

Scoop out the chilled dough and roll it into balls. Then, roll each ball in a mixture of sugar and powdered sugar.

Place the rolled cookies on the prepared baking sheets, making sure to leave enough space between them. Bake for 10-12 minutes or until the edges are lightly golden.

After baking, let the cookies cool on the baking sheet for about 5 minutes. Then, transfer them to a cooling rack to cool completely.
