Introduction
A few weeks ago I began adding a splash more colour to the allotment by planting some edible flowers. I am hoping to use them for adding instant personality to salads, drinks, puddings and more. I didn't realise that many flowers grown in the garden are edible and once I learned this, I had to explore the topic! Beyond my usual flower remedies and lotions and potions, a whole other world of floral fun awaits me!

Things to try
1) Elderflower Cordial (classic, refreshing)

- 1.5 litres water
- 1.2 kg granulated sugar
- 2 unwaxed lemons, thinly sliced
- 50 g citric acid (or juice of 2 lemons as alternative)
Method
1. Shake flowers gently to remove insects; do not wash (you’ll lose flavour).

3. Add elderflower heads, lemon slices and citric acid. Cover and leave in a cool place for 24–48 hours, stirring once.
4. Strain through muslin, squeeze out liquid, discard solids. Bottle and refrigerate for up to 2 weeks, or freeze/sugar-sterilise for longer storage.
Use: Dilute 1:6 with sparkling water, add to prosecco, or drizzle over desserts.
