Geonppang (Korean Hardtack Biscuits)

Preheat your oven to 180°C (350°F). Line a baking sheet with parchment paper.

In a large mixing bowl, combine the all-purpose flour, granulated sugar, fine sea salt, and baking soda.

Gradually add the water to the dry ingredients, mixing with a spoon or your hands until a stiff, shaggy dough forms.
