Prepare the Gravy

1. Melt 1 tablespoon of butter in a pan over medium heat. Once the butter is melted, add the mushrooms, leeks, and salt. Let them sweat for 5 minutes.
2. Add the sprig of thyme, parsley, rosemary and cook for another 2 minutes. 
3. Pour the broth into the pan and bring to a boil. Once the mixture boils, turn the heat down to maintain a low simmer. Cover and let it simmer for 90-120 minutes. The mixture should reduce to about 2 cups of broth. (Now is a good time to make the biscuits!)
4. When the mixture is about 10 minutes from being done, make the roux by adding the flour to a small pan over medium heat. Stir the flour with a whisk constantly until the flour turns golden brown (about 5-10 minutes). Then, add the butter and stir to combine until the butter is completely melted.
5. Add the roux to the mushroom mixture along with the Worcestershire sauce, soy sauce, white pepper, and truffle powder. Whisk the mixture for about 5-10 minutes until it thickens to your desired consistency.
6. Optional: If you like a chunkier gravy, then serve the gravy as is! If you prefer a smoother gravy, then use an immersion blender to get your desired consistency.

Prepare the Biscuits

1. Preheat your oven to 450°F.
2. In a medium-sized mixing bowl, combine the flour, baking powder, baking soda, and salt.
3. Add cold butter and coconut oil to the flour mixture. Break down the butter and coconut oil with a fork until the dough is crumbly.
4. Combine milk and apple cider vinegar. Then, make a hole in the center of the flour mixture, and add the milk mixture to the center. Slowly mix the flour into the milk mixture until combined.
5. Turn the dough out onto a lightly floured surface. Here you are going to make the laminated dough by folding the dough in thirds over itself. Then, with your hands, flatten out the dough and repeat the laminating process 5-6 times.
6. Using your hands again, flatten out the dough so it's about 1" thick. With a 2.5"-3" round biscuit cutter, stamp out your biscuits. Roll the leftover dough back out and repeat until you have all of your biscuits. You should be able to make about 12 biscuits.
7. Place the biscuits onto a greased baking sheet, and bake for 12-15 minutes or until the bottoms of the biscuits turn golden brown.
8. Serve warm along with the gravy, and enjoy!
