Start by choosing your brine from the list above. Each type will make enough brine to fill about 2 pints, which will pickle about 1/2 pound of scapes (1/4 pound per pint jar).
Prepare your garlic scapes by cutting them however you choose. You can do short segments, curly Q's, long straight pieces or just the blossom ends. Pack them into jars leaving 1/2 inch headpace.
Add the dry spices to each jar (or fresh dill fronds, if using).
If canning, prepare a water bath canner at this point. (Optional)
Prepare the brine by adding all the brine ingredients for the type you've chosen to a saucepan (just water, vinegar, salt and sugar). Bring it to a boil and stir to dissolve the salt/sugar.
Pour the boiling brine over the garlic scapes and spices in each jar, maintaining 1/2 inch headspace.
Seal with 2 part lids.
For refrigerator pickles, allow the jars to cool to room temperature and then store in the refrigerator. The pickles need at least 2 days for the spices to infuse before eating. They'll keep in the refrigerator for at least a month.
If canning, process the jars in a water bath canner for 10 minutes (or 15 mintues above 6,000 feet in elevation). Check seals and store any unsealed jars in the refrigerator for immediate use. Properly canned and sealed jars of garlic scape pickles will maintain peak quality on the pantry shelf for about 12 months, but be safe to eat so long as they're properly sealed. Refrigerate after opening.
