Instructions
-
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 fineβgrater zester, remove only the yellow outer peelβavoid the bitter white pith. -
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. -
Dry completely
-
Oven method:Β Set oven to the lowest temperature (170Β°F / 75Β°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 2β4 hours, stirring occasionally, until the zest is completely brittle and snaps when bent.
-
Dehydrator method:Β Dry at 95β105Β°F (35β40Β°C) for 6β10 hours, or until crisp.
-
-
Grind into powder
Let the dried zest cool completely. Transfer to a clean, dry spice grinder or highβspeed blender and pulse until a fine powder forms. For a smoother texture, sift through a fineβmesh strainer and regrind any larger pieces. -
Store
Immediately place the powder in an airtight glass jar. Store away from light, heat, and moisture.

Bakerβs Notes
-
Start with organic or untreated lemons:Β Because youβre using the peel, avoid conventional lemons that may have been sprayed with pesticides or coated with wax. If waxed, blanch or scrub well.
-
Donβt include pith:Β The white layer beneath the zest is bitter and will make the powder taste harsh.
-
Drying is key:Β The zest must be completely dry before grindingβany residual moisture will cause clumping and shorten shelf life.
-
Make it flavored:Β Add a vanilla bean, dried ginger, or rosemary while grinding for custom blends.
