Prep the Lemons: You will need 6-8 lemons for slices and juice. Rinse your lemons well. Slice 6 lemons into thin rounds about ⅛–¼ inch thick using a mandolin or sharp knife. Discard the end pieces.
6-8 whole lemons
Make the Syrup Base: In a small bowl, whisk together the sugar and pectin. This prevents clumping.
1 lb sugar, 1 ½ tablespoons Ball Classic Pectin
Add the lemon juice to a saucepan, then slowly whisk in the sugar and pectin mixture. Cook over medium heat until the mixture turns clear and looks like a thickened syrup. Be sure to stir gently and steadily so it does not burn.
4 tablespoons fresh squeezed lemon juice
Combine with Lemons: Place the sliced lemons into the saucepan with the hot syrup. Use a spoon or spatula to toss gently so the slices stay intact and don’t break apart.
Cook the Lemons: Cover the pan with a lid and cook for 6 minutes over medium-high heat.
Remove the lid, then press the lemons gently under the syrup with a slotted ladle. Do not stir, just press, to keep the slices whole. Cover again and cook for another 6 minutes. Turn off the heat.
Rest and Store: Let the lemons rest in the pan for 10 minutes.
Carefully transfer the lemon slices into a tall glass jar. Pour the syrup over the top so the slices “float” freely and don’t stick together.
Bonus Syrup: Any leftover syrup can be saved as a lemon syrup for pancakes, waffles, or ice c
