Pickles with cilantro and Lemon zest

I pickles cucumber and carrots with cilantro and lemon zest. It turned out pretty good. I really like the subtle cilantro flavor in the veggies. The lemon zest gives it a bit too much bitterness, possibly because the zest is sliced too thick, containing also the bitter white parts. 

I did another one with just cucumbers, cinnamon and cloves in red wine vinegar. Pretty good!
