What you'll need:

• Flowers
• Baking tin 
• Greaseproof paper
• Scissors
• Essential oil
• Spray bottle, if possible 
• Citrus fruits (optional)
• Fresh herbs (optional)
• Whole spices (optional)

What to do: 

1. Collect some flowers to use for making the pot pourri. Make sure you have permission from the gardener! Any kind of flower are fine, but larger blooms with a strong scent are ideal. Try roses, honeysuckle, lavender or clematis. 
2. Preheat your oven to 80-90˚C. 
3. Lay greaseproof paper in a baking tray/sheet. Place whole flowers on the greaseproof, or remove individual petals and arrange them in a single layer. 
4. To add scent to your potpourri, cut and add thin slices of citrus fruits, or tuck in springs of rosemary, lavender, or thyme to the mix. You can also add whole spices, such as cinnamon sticks, star anise, or cloves.
5. Add around 10 drops of an essential oil to one tablespoon of water in a small spray bottle, and spray your potpourri ingredients.
6. Place the tray of potpourri into the oven. Dry in the oven for at least two hours, or until the flowers are brittle but not burnt. Citrus fruit slices will take longer to dehydrate fully.
7. Leave to cool then arrange in a bowl.
