Wash the orange thoroughly.
Use a vegetable peeler, box grater or paring knife to carefully remove the zest from the orange, avoiding the bitter white pith beneath.
Place the orange zest into your clean 8oz glass jar.
Pour 8 oz of vodka over the orange zest, ensuring the zest is fully submerged.
Tightly seal the jar with its lid. Give it a good shake to mix the contents.
Place the jar in a cool, dark place away from direct sunlight, like a pantry or cabinet, for 6 weeks. Shake the jar gently every couple of days to aid the infusion process.
After 6 weeks, strain the extract through a coffee filter or fine mesh sieve into a clean bowl to remove all the solid pieces.
Pour the strained extract into a small airtight container or amber glass bottle. Label it if desired.
Keep your homemade orange extract in a cool, dark place. It's now ready to use in your favorite recipes!
