Instructions
Wash the lemons thoroughly with warm water. Cut each fruit lengthwise into quarters and carefully remove all the peel pieces.

Using a sharp knife, scrape away the white pith from the inside of each peel - this step is crucial since the pith adds unwanted bitterness.
Place the peels in a saucepan and cover completely with water. Bring to a boil and cook for 10 minutes, then drain. Repeat this blanching process to remove excess bitterness.
Strain the peels, and add them back into the pot. Cover with a little water and boil for about 5 minutes. Repeat this step a second time. (or even a third if you find your peels still too bitter)
water
Drain the blanched peels thoroughly and weigh them. You'll need an equal weight of granulated sugar (so 7oz/200 gr of peels equals 7oz/200 gr of sugar).
granulated sugar
Return the peels and sugar to your saucepan. Pour in just enough water to cover them and bring to a boil. Reduce the heat to low and simmer gently for about 1 hour, stirring occasionally. Add more water as needed - you want a thick, glossy syrup coating the peels.
Remove the peels from the syrup and let excess liquid drip off. Arrange them in a single layer on a parchment-lined baking sheet. Let them air-dry for 2-3 days, or speed up the process by placing them near a heating vent. For faster results, dry them in your oven at the lowest setting (around 50°C/120°F) for 2-3 hours, checking frequently.
Then cut the peels into small cubes, optionally dust with powdered sugar to remove any leftover moisture and store in an airtight container in a cool place.
