Ingredients

• 6–8 organic, unwaxed lemons (or as many as you like)

Instructions

1. Wash and zest
   Scrub the lemons thoroughly under warm water. If they are not organic or have a wax coating, blanch them briefly in boiling water for 10 seconds, then rinse.
   Using a microplane or fine‑grater zester, remove only the yellow outer peel—avoid the bitter white pith.

2. Spread the zest
   Spread the fresh zest in a thin, even layer on a baking sheet lined with parchment paper (for oven drying) or on the trays of a food dehydrator.

3. Dry completely

   • Oven method: Set oven to the lowest temperature (170°F / 75°C). Place the zest in the oven with the door slightly ajar (use a wooden spoon to prop it open) to allow moisture to escape. Dry for 2–4 hours, stirring occasionally, until the zest is completely brittle and snaps when bent.

   • Dehydrator method: Dry at 95–105°F (35–40°C) for 6–10 hours, or until crisp.

4. Grind into powder
   Let the dried zest cool completely. Transfer to a clean, dry spice grinder or high‑speed blender and pulse until a fine powder forms. For a smoother texture, sift through a fine‑mesh strainer and regrind any larger pieces.

5. Store
   Immediately place the powder in an airtight glass jar. Store away from light, heat, and moisture.

Baker’s Notes

• Start with organic or untreated lemons: Because you’re using the peel, avoid conventional lemons that may have been sprayed with pesticides or coated with wax. If waxed, blanch or scrub well.

• Don’t include pith: The white layer beneath the zest is bitter and will make the powder taste harsh.

• Drying is key: The zest must be completely dry before grinding—any residual moisture will cause clumping and shorten shelf life.

• Make it flavored: Add a vanilla bean, dried ginger, or rosemary while grinding for custom blends.
