Mix the ground spices together with a fork or small whisk until well combined. If using a jar, measure the spices directly into the jar, secure the lid, and shake to combine. Store homemade chai spice in a dark dry cupboard or pantry as you would any other spice. Use as needed.
Notes
You can use whole spices instead of ground. If using whole spices, toast them in a dry, heavy-bottomed skillet until fragrant before grinding. This will give you a more intense flavor profile.
Adjust the amount of each spice gradually, as some (like clove and cardamom) can quickly overpower the blend.
Storage For Homemade Chai Spice
Store your chai spice blend in an airtight container in a cool, dark place away from direct sunlight and heat sources. Glass jars or metal tins best preserve freshness. While the blend can last up to a year, it's best used within 3-6 months for optimal flavor. If you notice any loss of aroma or clumping, it's time to make a fresh batch.
