If you're in doubt, elderflowers look like this and smell of summer. In fact, it's actually best to pick them on a sunny day as that's when they have the most flavour.
Elderflower cordial (makes 500ml)
- 10-20 elderflower heads, shaken clean of bugs but not rinsed
- 350ml caster sugar
- 1 lemon, cut into slices
- Pour 500ml boiling water over the elderflower heads, sugar and lemon slices.
- Leave to steep until cool, or just overnight.
- Check the taste, and add more sugar if necessary.
- Strain the liquid using a couple of layers of kitchen roll or a teatowel (clean!) in a sieve.
- Serve with gin and ice or keep it for a few days in the fridge. Elderflower cordial also freezes well.
