They say you learn something new everyday - well here's one, when the beets are cooked they float to the surface when boiled in lightly salted water! When you think about it that means you can throw in different sizes, and just pick them off when they are done - no stabbing/jabbing guessing.
Herb and Spice mix - note Sea Salt
Reserve the chili, fennel sprigs and lemon, those go in the jar raw with the cooked beets
Pour mix into jars, use a spoon to add bits of seeds etc. and place in pickling bath (again, see the malt and mustard posting)
I also srinkled about half a teaspoon of dried coriander leaf into each jar before sealing.
