In a bowl, dissolve well lime in 2kgr-3kgr of water and then strain.
In this mixture place the cherries and leave for 2h-3h, stirring often.
Then wash thoroughly cherries and remove the seeds.
In a saucepan put the cherries and the sugar and leave overnight.
The next day, add water and boil for 1h-1.5h up to tie the syrup.
In the end, add the vanilla and lemon drops and cover for 2h-3h the saucepan to melt granules of sugar fortunes.
To avoid sugarcoat, after cooling take with a spoon a little syrup and let it fall into the saucepan.
If the drop is fat when it falls in the syrup is okay. If not you have to boil it again for a while to tie up well and not spoil.
