Frequently Asked Questions
Can I use the leftover lemons after peeling the zest?
Absolutely. The peeled lemons are still perfect for juicing. They’ll keep in the refrigerator for a few days. Juice them and freeze the juice in ice cube trays for future use, or use it immediately in dressings, marinades, or beverages. No part of the lemon goes to waste.
What if I don’t have a spice grinder?
A clean coffee grinder works identically. You can also use a mortar and pestle for a more hands-on approach; it will yield a slightly coarser powder but works perfectly well. A high-speed blender can also work if you have a small jar attachment, but the zest may need a little longer and you’ll need to scrape down the sides. The key is to ensure the zest is bone-dry so it grinds easily.
Can I make lemon powder from pre-zested lemon peel?
Yes, you can buy dried lemon peel (often in the spice aisle) and grind it into a powder, but it won’t be as intensely flavored as homemade from fresh zest. Pre-dried peel has already lost some of its volatile oils. Starting with fresh lemons and drying them yourself yields a far superior product. That said, grinding store-bought dried peel is a quick shortcut for a milder powder.
How much lemon powder equals the zest of one lemon?
Roughly ¼ to ½ teaspoon of lemon powder provides the flavor equivalent of the zest from one medium lemon. Start with a pinch and add more to taste; the intensity of homemade powder can vary based on how fresh your lemons were and how long you dried them. It’s always easier to add than to take away.
Is lemon powder just the same as citric acid?
No, they are completely different. Citric acid is a sharp, sour white powder that adds acidity without much flavor. Lemon powder is dried, ground lemon zest—it contains the essential oils and provides a fragrant, lemony taste without significant sourness. The two can be used together: lemon powder for flavor, citric acid for tartness.
Homemade Lemon Powder
Make your own bright, aromatic lemon powder with just fresh lemons and a little patience. A pinch transforms desserts, rubs, teas, and savory dishes with pure lemon essence.
Prep Time:
10 minutes
Drying Time:
2–12 hours
Total Time:
2–12 hours 10 minutes
Yield:
About 2–3 tablespoons powder
Ingredients
- 4–6 large organic lemons, well washed and dried
Equipment
- Vegetable peeler or citrus zester
- Dehydrator OR oven
- Spice grinder, coffee grinder, or mortar and pestle
- Airtight glass jar for storage
Instructions
- Wash and dry the lemons thoroughly.
- Using a vegetable peeler, remove the yellow zest in wide strips, avoiding the white pith as much as possible.
- Dry the zest strips until completely brittle: use a dehydrator at 115°F–125°F for 6–12 hours, OR an oven on its lowest setting (170°F–200°F) with the door slightly open for 2–4 hours. The zest should snap when bent.
- Cool completely to room temperature.
- Grind the dried zest in a spice grinder in short pulses until it becomes a fine powder. Sift through a fine-mesh strainer if any coarse bits remain, and re-grind those.
- Transfer the powder immediately to an airtight jar. Store in a cool, dark place for up to 1 year.
Notes
- Use organic lemons if possible, and scrub well to remove any wax or residue.
- Keep the temperature low during drying to preserve the essential oils; do not let the zest brown.
- Lemon powder can be used in baking, rubs, teas, frostings, and anywhere you want pure lemon flavor without added liquid.
- To make a citrus blend, combine equal parts lemon, orange, and lime powders. For a seasoning, mix with salt and pepper.
