f using fresh lemons, wash and dry them thoroughly. Zest only the yellow outer layer and avoid the white pith. Spread the zest on a baking sheet and dry at 170°F (75°C) for 5–7 minutes or air-dry for 24 hours until completely dry.
Place cracked black pepper in a dry skillet over medium-low heat. Toast for 2–3 minutes while stirring constantly until fragrant. Remove from heat and allow to cool fully.
In a medium mixing bowl, combine dried lemon zest, toasted black pepper, sea salt, garlic powder, onion powder, and any optional herbs.
Mix thoroughly for 1–2 minutes until evenly combined and no clumps remain.
Taste a small pinch and adjust salt, pepper, or lemon zest to your preference.
Transfer to an airtight glass jar and store in a cool, dry place for up to 3 months.
