Step 1

Slice the lemons evenly, from 1/8 to 1/4-inch thick. You can get approximately 8 slices per lemon, depending on the size of the lemon.

Step 2

Place the slices on a metal cooling rack over a baking sheet or a parchment paper lined baking sheet.

Step 3

Bake in the oven to the lowest temperature (for my oven it's 170ºF/77ºC) until completely dry, approximately 4 to 5 hours.

Step 4

For even drying, rotate the baking sheets every hour or two.

Step 5

Store in an airtight container until ready to use.
