Remove pods and white membranes of the pomegranates.
Press out the juice of the pomegranates with a lemon squeezer. You will be surprised when you try it, because it is very practical to get pomegranate juice.
From 3 pomegranates you should get 1 1/2 cup juice.
Put the juice (and the pulp if you like but it will be a little bit bitter then) in a glass jar.
Add peeled & scraped lemon and vodka.
Seal the jar and let wait 2 weeks.
Filter with cheese cloth if you added the pulps.
Then it is your choice to add sugar. If you like it as it is, start tasting.
If you don’t, boil sugar with water make a syrup (3/4 cup of syrup) and add it to the pomegranate vodka mixture.
The grenadine has a deep colour and a rich flavour.
