The cucumber I used for this was squatter and fatter than a standard supermarket one. It had quite large seeds which I removed. The chilli I used was quite hot - you need some heat but treat amount with caution. I used one 50ml bottle of Edinburgh Gin. You can of course, use a different type! Wash and heat your jars in the oven to sterilise them before filling. If you like your pickly crunchy eat after a few days, otherwise it will keep for weeks.
