Prepare a baking sheet with parchment paper or a silicone baking mat.
Heat three tablespoons of water on the stove and preheat the oven to 375°F.
When the water is ready, whisk it with one tablespoon of ground flax seed in a small bowl. It will have a gooey consistency because it will have the binding property of an egg.
In a large bowl, mix the flour, sugar, baking powder, baking soda, and salt.
Cut in three tablespoons of cold butter and mix with a pastry blender until the butter is in small, pea-sized crumbs.
Add the buttermilk to the flax "egg" and whisk to combine. Then add the wet to dry and mix.
Rinse the chives and lemon balm and chop them finely on a cutting board. Feel free to experiment with any other savory herbs such as rosemary or thyme. Fold the herbs into the dough until they are evenly dispersed.
Using a small, greased measuring cup, scoop dough onto the baking sheet. Each biscuit should be roughly 1/4 cup of dough.
Bake the biscuits for about 15 minutes at 375°F. Test them with a toothpick when they are getting slightly golden to make sure it comes out clean. Enjoy!
