How to make elderflower cordial

This one is well worth making - summer in a bottle,and will keep for a long time, either processed in a hot water bath or frozen in eg plastic milk containers. Drink it with soda or plain water and lots of ice, drizzle it over cakes, use to flavour stewed fruit. icecream, whipped cream etc, mix with gin or vodka..........endless uses :) 1 colanderful of flowers, as much green removed as possible, but I don't worry too much water to cover sugar Place flowers in pan and cover withcold water; simmer for about 15 minutes or so, strain, and measure the liquid. Return it to the pan and add 12 ox white sugar to each pint of liquid. Heat getnly until sugar is thoroughly dissolved. Leave to cool, then store/process/drink as desired. Use diluted as squash; also makes lovely summery ice lollies
