Elderflower joy

Every year I make a couple of gallons of elderflower cordial:

10 or so big elderflower heads
1 pt water
900g sugar
2 unwaxed lemons
40g citric acid
(these quantities are a bit approximate, as they depend on how sweet/tart/ lemony you want it)

Heat the water to boiling on stove and dissolve the sugar in it. Take off the heat and stir in the citric acid. Grate the peel from the lemons into the syrup and then cut the lemons themselves into big slices and add them too.

Leave the mixture to steep for 24 hours and then strain through muslin, squeezing hard to get the lemon flavour properly into the syrup. Bottle.

This quantity will make between 2 and 3 pints of cordial. It will keep in the fridge for quite a few weeks. If, like me, you make it in vast quantities, I like to put it in those oblong plastic 1pt milk bottles and freeze it so you can have homemade elderflower cordial all the year round.
