If you've been out picking Elderflowers to make cordial over the last few weeks, here's a quick idea that'll make good use of some of your batch. It's a variation on a classic Margarita - personally, I tend to steer clear of Triple Sec that's often used too (bad experience in my youth). It matters not though - Tequila and Elderflower get on fabulously well.
15ml Elderflower cordial
Juice of two Limes
Crushed Maldon Sea Salt
Rub the rim of a glass with half a cut lime, then dip in salt. Rattle the ingredients together in a cockail shaker with a few ice cubes, then serve immediately.
