Grandma’s Homemade Mustard Pickles are a cherished family recipe, combining sliced cucumbers, green tomatoes, onions, cauliflower, and green peppers in a zesty mustard sauce. The perfect balance of tangy and sweet flavors makes these pickles a delightful and nostalgic treat enjoyed for generations.
This old-fashioned pickle recipe is different from most other pickles. Fresh cucumbers and onions are pickled in a mustard sauce infused with turmeric and celery seed.
This particular mustard pickle recipe is a New England favorite! It originated in Maine and was handed down to me by my husband’s Grandmother (bless her soul), who has since passed. The sauce is tangy and thick, and this recipe is perfect for the end of the garden bounty.
It was grammy Opal’s way of using up every last bit of the delicious garden bounty she worked so hard to grow all spring and summer long.
To be honest, I always looked forward to the phone call asking for my help getting the vegetables ready because I craved the thick mustard sauce pickles with their piquant sweetness.
How to Make Homemade Mustard Pickles
First, gather all of your ingredients, and anyone at all that you can con into helping you wash and chop up all the veggies.
Put all the chopped veggies in a very large pot with enough COLD water to Cover. Sprinkle them with canning salt and let the whole pot sit overnight, covered. (Do not refrigerate).
In case you’re wondering what’s the difference between canning salt and table salt, canning salt is pure, lacking preservatives. Table salt contains additives such as potassium iodide or sodium iodate, etc. Using table salt can cause the jars of pickles to become cloudy or dark.
The next morning, drain and rinse the veggies very well. Combine the ingredients for the sauce in a heavy large stockpot.
Bring the mustard sauce to just under the boiling point. At this point, it will be quite thick, then add veggies.
Ladle into canning jars, and be sure to leave the proper amount of headspace! Process in a water bath canner for fifteen minutes.
Here are a few of the finished jars, not that they last very long. These have been my husband’s favorite since he was a child. Our own sons adore them as well.
If you’d rather have old-fashioned mustard pickle spears, just use cucumbers in place of the cauliflower. Of course, you’ll need to brine them overnight as well.
