Pull every spice you need and arrange them in the order you'll use them. This prevents double-measuring or forgetting an ingredient—I line them up left to right like a mise en place. Use a small spoon or measuring spoon you've designated for spice work only (not the one you use for baking, as cross-contamination changes flavors). Clear your counter completely so you're not working around clutter.

Cinnamon is your anchor spice—it's mild enough to carry the blend but prominent enough to define it. Measure 3 tablespoons directly into your glass jar. I use the spoon-and-level method: spoon the cinnamon into the measuring spoon, then level with a straight edge rather than scooping directly from the container, which compacts the spice and throws off your ratios. Tap the jar gently to settle the cinnamon into the bottom.

Now layer in your cardamom (1 tablespoon), ginger (1 tablespoon), allspice (½ tablespoon), cloves (½ tablespoon), and nutmeg (½ tablespoon). Add each one in its own layer rather than stirring between additions. This creates distinct flavor pockets that you'll blend together in the next step, ensuring even distribution. Your jar should be about two-thirds full at this point. Add the black pepper and sea salt last—these are your precision ingredients that tie everything together.

Screw the lid on tight. I'm talking sealed-tight, no-spillage-when-inverted sealed. Now shake vigorously for exactly 30 seconds. Set a timer—this matters because 30 seconds distributes everything evenly without over-blending into a paste. After 30 seconds, tip the jar upside down and shake for another 15 seconds to ensure any spices that settled get re-incorporated. Open the lid and do a visual check: you should see a relatively uniform mixture with no obvious clumps of single spices visible.

Use a waterproof label (or masking tape and permanent marker if you're keeping it real) to write the date you made this blend and the contents: "Chai Spice Blend - [Date]." Store in a cool, dark cabinet away from direct sunlight and heat sources—the back of your spice cabinet is perfect, not above your stove where steam and temperature fluctuations degrade spice potency. A sealed glass jar in these conditions keeps your blend aromatic and potent for a full year. Shake briefly before each use to re-incorporate any oils that have settled.
