Matters needing attention in soaking dried lemon slices in water
Hot water is suitable for soaking dried lemon slices at 60-70℃.
When using lemonade instead of boiled water to quench thirst, dry lemon slices should be gently soaked in water. A large piece of dried lemon with skin can be soaked in 1 liter of water and poured into 3-4 small cups. Generally brew for 2-3 times. You can change it for a new one when it doesn't smell like lemon.
If you put more lemon slices in the water, you can add sugar or honey to balance the sour taste.
