● 1 kg watermelon rinds, without the red flesh
● 1 kg sugar
● 40 g water
● 1 sachet vanilla
● 3 lemons
● Juice of half a lemon
Clean the outside green rind from the red flesh, leaving very little flesh on the white part.
Then slice in wedges.
Put them in a bowl with water and the juice of 3 lemons.
Put a weight over the bowl so the rinds are fully immersed in the water and leave it for 3 hours.
Next, drain well, put the rinds in a large pot, add the sugar, water and simmer on low heat for 15 minutes until the sugar dissolves, removing any foam with a spoon.
Turn off the heat and leave it overnight.
The next day, boil again for the syrup to thicken.
Just before turning off the heat, add the vanilla and the lemon juice.
