Why Make Lemon Powder?
-
Zero waste – uses whole lemons (peel + pulp, minus juice).
-
Long shelf life – lasts months in a jar.
-
Intense, tangy flavor – no additives.
Ingredients
-
6–8 medium organic lemons
Why organic? Conventional peels often have wax and pesticides. If using non-organic, scrub well with hot water and vinegar.
Equipment Needed
-
Vegetable peeler or zester
-
Baking sheet with parchment paper
-
Oven or dehydrator
-
Spice grinder / blender
-
Fine-mesh sieve (optional)
-
Airtight glass jar
Method
1. Prepare the lemons
-
Wash and dry the lemons.
-
Zest or peel off the yellow outer skin (avoid the white pith – it adds bitterness).
-
Remove any white pith from the peeled strips with a knife, or use only zest for a milder powder.
2. Dry the peels
Option A – Oven (lowest heat):
-
Spread peels on a parchment-lined baking sheet.
-
Dry at 80–90°C (175–195°F) for 2–3 hours until brittle. Leave the oven door slightly ajar.
Option B – Dehydrator:
-
Dry at 50–55°C (120–130°F) for 8–12 hours.
Option C – Sun/air (warm climate):
-
Cover peels with a thin cloth and leave in direct sun for 2–3 days until bone-dry.
3. Grind into powder
-
Break dried peels into small pieces.
-
Blitz in a spice grinder for 10–20 seconds until fine.
-
Let dust settle before opening.
4. Sieve (optional)
-
For an ultra-fine powder, sift through a fine-mesh sieve. Re-grind any coarse bits.
5. Store
-
Transfer to an airtight glass jar.
-
Keep in a cool, dark, dry place.
Uses for Lemon Powder
-
Lemon pepper seasoning – mix 2 parts lemon powder + 1 part black pepper + salt
-
Tangy rub for chicken or fish – add to oil with garlic powder and herbs
-
Brighten sauces and soups – sprinkle in at the end
-
Instant lemonade mix – combine with sugar and water
-
Baking – add to scones, shortbread, or icing (1 teaspoon powder = zest of ½ lemon)
-
Salad dressing – whisk with oil and honey
-
Herbal tea – steep with mint or ginger
-
DIY bath salts – mix with Epsom salt and baking soda
Storage & Shelf Life
-
Pantry – 6 to 12 months (if fully dry)
-
Fridge or freezer – even longer
Signs it has spoiled – dull color, musty smell, clumping (moisture).
Tips for Best Results
-
Grind in short bursts to avoid heating the powder (heat dulls flavor).
-
Dry completely – any moisture leads to mold.
-
Double the batch – powder reduces volume by about 90%.
-
Label the jar with the date and contents
