Place all the ingredients in a saucepan on medium heat.
250 ml water, 200 g white sugar, 60 g dried hibiscus flower, 1 Tbsp lemon juice
Bring everything to a simmer, and leave to simmer for 10 minutes, stirring a couple of times.
Rest for 10 minutes for the flavour and colour to deepen, then strain into sterilised bottles. Just wash your bottles in hot soapy water and rinse well, or sterilise them as in the article above.
Store in the fridge, for up to 1 month. Serve as suggested.
