Once all gin has been drunk (awwww) how about reusing that bottle. You can make your own chilli oil by adding dried chillies to oil and placing a speed pourer for easy use.
Heat the oil in a saucepan over a medium heat (please take care) and add dried chilli flakes until the chillies gently sizzle. Allow to cool and pour into a sterilised airtight Graveney Gin bottle.
This makes a create gift!
Please make sure that you sterilise the glass bottle and use dried produce only.
