I've made that same recipe and they are very good! I have some in the fridge now.
I wish I had some left! I made the mistake of opening the jar when I had a few friends over! I was lucky to keep all my fingers.
I will make more "pub eggs", and as several have noted above, a dozen is a small batch, so I will be making more this time around.
I never would have thought of using cinnamon in pickled eggs, but I like it!
