If the product doesn't seem wet enough, add another mix of the vinegar/sugar/seasoning recipe to it and cook it again. You don't want it too dry for fear the veggies won't get pickled properly. Better a little too wet, than too dry. If too wet, you can adjust it as you fill the jars.
Pack hot relish into hot jars, leaving 1/4 inch headspace. Adjust two piece caps. Process 10 minutes in a boiling water canner. Yield: about 4 half-pints.
