Throughout the Mediterranean caperones (which are large capers) grow everywhere, wildly and in profusion. They are wonderful in olive oil infused with garlic or chillies and make a great tapa. 

The ancient Greeks used them to prevent a build-up of gas in the stomach but I just eat them because they are most moreish. Very.

These caperones were donated to me by my neighbours 
And after trying these you won’t go back to those tiny ones sold in jars at British supermarkets. I promise. OK, OK I accept that the small ones work well when making a sauce for Skate, for example.
