blueberry pickle??!!

Stumbled upon this pickle recipe collection.
How cool does this blueberry pickle look?!

There is a blueberry farm just outside the city and ever since last year Lisa and I have talked about spending an afternoon in that field picking.
My mind always goes straight to making jam when it comes to preserving blueberries, but this might be a fun add on :) To be honest I wouldn't even know what this should taste like - I've never had blueberries in a savoury way - so this should be interesting. If it doesn't turn out great I'll love it for the colour anyway haha.
