Ooooo. Sounds like a GREAT idea!
Embarrassed to say that I don't know what seasoning salt is though. Can I use Redmonds whole salt or some other salt instead? Can I use all apple cider vinegar instead of adding white vinegar?

I'm definitely going to try this. We love pickled things so this might be the ideal way to get a little heart every day.
Thanks!

Seasoning salt is just regular old table salt mixed with your favorite spices and herbs.  Here's the seasoning salt recipe that I use. 
6 tablespoons salt
1/2 teaspoon dried thyme leaves
1/2 teaspoon marjoram
1/2 teaspoon garlic salt or garlic powder
2 1/4 teaspoons paprika
1/4 teaspoon curry powder
1 teaspoon dry mustard
1/4 teaspoon onion powder
1/8 teaspoon dill weed
1/2 teaspoon celery salt
Mix all the ingredients together and use as needed.  What I usually do is make up 2 or 3 batches at once and just measure out what I need.  And yes you can most certainly use all apple cider vinegar if you want, that's what I use.  Good luck and let me know what you think.
