First up, extract the juice from the Pomegranates by whatever means you have available. I don't have a fancy contraption for this, so run them through a regular juicer, then squeeze the remaining pulp through a piece of cloth before giving everything a quick run through a fine mesh sieve
Place 300g of the resulting Pomegranate Juice in a small, thick-bottomed saucepan, along with 40g of White Sugar and 15g of Lemon Juice. Then simmer for approximately 30 minutes. Keep a close eye on it for the final 10 minutes, because syrups can go nuclear very fast
Once the sauce has become thick enough to coat the back of a spoon, add the remaining 300g of Pomegranate Juice and 150g of White Sugar and stir continually until the Sugar has dissolved, ensuring that the liquid doesn't boil
Once dissolved, turn off the heat, add 2g of Orange Blossom Water and give the whole thing a good stir
Transfer your syrup to a suitable storage container or glass jug and leave to cool
