Step 1

Prep the lemons: Wash and dry the lemons well. Trim off the ends and slice into very thin rounds (as thin as possible). Remove any seeds as you go.

Step 2

Fry the slices: In a medium skillet, heat the olive oil over medium heat until it starts to shimmer (but before it smokes). Carefully slide the lemon slices into the oil (if you have a splatter guard, this would be a good time to use it). Cook, tossing occasionally, until the lemon peels crisp (3 to 5 minutes).

Step 3

Drain: Remove the skillet from the heat. Use a slotted spoon to transfer the lemons to a plate lined with a paper towel. Immediately season with a big pinch of salt and the sumac, if using.

Step 4

To use: Use the fried lemon rings as a condiment or as garnish. Allow the lemon-infused oil to cool before using as a finishing oil or for dipping bread.
