Pickled Brussels sprouts, often playfully referred to as “Frog Balls,” are a tangy, crunchy, and slightly sweet preserved vegetable that adds a burst of flavor to many dishes. Despite the unusual name, this recipe is simply a creative way to transform fresh Brussels sprouts into a delicious pickled snack. The sprouts are first lightly cooked to soften them slightly while keeping their texture, then submerged in a flavorful brine made with vinegar, sugar, and aromatic spices.
These pickled sprouts are known for their balance of flavors. The vinegar provides a bright acidity, the sugar adds a touch of sweetness, and the spices contribute a subtle warmth and depth. Once prepared, the sprouts absorb the brine over time, developing a rich, bold taste that becomes even better after resting for several hours or days.
They are perfect as a snack straight from the jar, served on appetizer trays, or used as a unique topping for sandwiches and salads. With their vibrant color and crisp texture, pickled Brussels sprouts are also an excellent addition to charcuterie boards or relish trays. The preparation process is straightforward, making this recipe accessible even for beginners interested in homemade pickling.
Ingredients
Brussels Sprouts
- 1 1/2 lbs Brussels sprouts (about 4 cups)
Pickling Brine
- 1 1/3 cup white vinegar (5% acidity)
- 2/3 cup sugar
- 1 tablespoon mustard seed
- 1/2 tablespoon celery seed
- 1/3 teaspoon turmeric
- 1/3 teaspoon red pepper flakes (optional for a little heat)
Instructions
Step 1: Prepare the Brussels Sprouts
Begin by thoroughly washing the Brussels sprouts under cold running water to remove any dirt or debris. After rinsing, inspect each sprout carefully and remove any tough, damaged, or discolored outer leaves.
Next, trim the hard stems at the base of each sprout using a sharp knife. If some of the Brussels sprouts are particularly large, cut them in half so they cook evenly and absorb the pickling brine more effectively. Smaller sprouts can remain whole.
This preparation step ensures that the sprouts are clean, tender, and ready to absorb the flavorful pickling liquid.
Step 2: Blanch the Sprouts
Fill a large pot with water and add canning salt (approximately 4 teaspoons of salt for every gallon of water). Bring the salted water to a full boil over medium-high heat.
Once the water reaches a rolling boil, carefully add the prepared Brussels sprouts to the pot. Allow them to cook for about 4 minutes. The goal is to soften them slightly while preserving their firm texture and bright green color.
Avoid overcooking, as the sprouts should remain somewhat crisp so they maintain their structure during the pickling process.
After 4 minutes, remove the pot from the heat and immediately drain the Brussels sprouts in a colander. Set them aside and allow them to cool slightly while you prepare the pickling brine.
Step 3: Prepare the Pickling Brine
In a medium saucepan, combine the white vinegar, sugar, mustard seeds, celery seeds, turmeric, and red pepper flakes if you are using them.
Place the saucepan over medium heat and bring the mixture to a gentle boil while stirring occasionally. The sugar should dissolve completely into the vinegar, forming a well-balanced sweet and tangy brine.
Once the mixture reaches a boil, reduce the heat slightly and allow it to simmer for about 5 minutes. This brief simmer allows the spices to release their aromas and fully infuse the brine with flavor.
When finished, remove the saucepan from the heat but keep the brine hot.
Step 4: Fill the Jars
Prepare clean jars suitable for pickling. Carefully pack the blanched Brussels sprouts into the jars, arranging them so they fit snugly but without crushing them.
Leave enough room at the top of the jar to allow space for the pickling liquid. Proper spacing ensures that the sprouts remain fully submerged and that the jar can be sealed correctly.
Step 5: Add the Hot Brine
Slowly pour the hot pickling brine over the Brussels sprouts in each jar. Make sure the liquid completely covers the sprouts.
Leave approximately 1/2 inch of headspace at the top of the jar. If small air bubbles appear trapped between the sprouts, gently tap the jar or use a utensil to release them.
If needed, adjust the liquid level to maintain the proper headspace.
Step 6: Seal the Jars
Place the lids on the jars and secure the rings until they are finger-tight. The jars should be sealed firmly but not overly tightened.
Step 7: Process the Jars
Place the sealed jars into a boiling water bath or a steam canner and process them for 10 minutes. This step helps create a proper seal and ensures the pickles can be stored safely.
Once the processing time is complete, carefully remove the jars from the water using jar lifters and place them on a towel on the countertop.
Step 8: Cool and Store
Allow the jars to cool completely at room temperature for 24 hours without disturbing them. During this time, the lids should seal properly.
After cooling, store the sealed jars in a cool pantry or storage area for up to one year. If a jar is opened, it should be refrigerated.
For the best flavor, allow the pickled Brussels sprouts to sit for about 3 to 4 weeks before eating. This resting period allows the sprouts to fully absorb the brine and develop their signature tangy, sweet, and slightly spicy flavor.
