Your post has inspired me to go to Penzey’s (a dangerous place!) to buy more sea salt and some nice spices to try as flavors. Knowing my hatred for zesting citrus, I bought their dehydrated version — should I grind that before mixing it in with the salt? They also recommended lavender, so I’m going to mix up a batch of that — I haven’t yet decided whether to grind the flowers and mix in, or make a muslin bag (I know I have some muslin around here somewhere…) and put them in a jar together for a couple of weeks.
I also dropped in to another addictive place, the Tuesday Morning store, where I found a set of three jars of sea salt marked down to $2! Hawaiian, Mediterranean and Pure Sea Salt. This should get me on a cooking binge again.
