Cook the jar in boiling water for several seconds and let it dry naturally.
Wear your gloves and then wash the lemon with pinch of salt on surface;set aside to dry.
Prepare a clean board and slice the lemons. Lay lemon slices in the bottle of the jar and pour enough honey to cover. Cover the jar and keep in fridge. Every two days, stir the lemon and honey from bottom to top with a clean scoop or chop sticker.
Enjoy after one week but this can be kept for over a month as long as you are using a clean scoop every time.
When serving, use warm water (around 60 degree C) to make a warm drink at first (1 tablespoon liquid+2 lemon slices and 1 cup warm water). And if you prefer a cold drink, add ice cubes. Using cold water directly is not recommended.
