Yellow mustard pickled eggs made with hard-boiled eggs in a tangy mustard and turmeric brine with sliced onions, mustard seeds, peppercorns, celery seed, and garlic.
In a saucepan, combine the white vinegar, water, sugar, salt, yellow mustard, and ground turmeric. Bring to a light simmer over medium heat, stirring until the sugar and salt are fully dissolved.
Remove the brine from the heat and allow it to cool to room temperature.
Layer the peeled hard-boiled eggs, sliced onion, mustard seeds, peppercorns, celery seed, and garlic in a clean quart-size mason jar.
Pour the cooled brine into the jar, covering the eggs and seasonings. Fill to just below the band line.
Place a canning weight into the jar to keep the eggs fully submerged in the brine.
Cover the jar and let it stand at room temperature for 1 hour.
Transfer the jar to the refrigerator and refrigerate for at least 24 hours before serving. For best flavor and color, refrigerate for 1 week before serving.
Notes
Allow A Full Week: While the eggs can be eaten after 24 hours, 1 week of refrigeration produces the best flavor and color.
Keep Eggs Submerged: Use a canning weight or other food-safe weight to ensure the eggs remain below the surface of the brine.
Expect Turmeric Settling: Ground turmeric may settle to the bottom of the jar during storage. This is normal.
Store In The Refrigerator: These are refrigerator pickled eggs and should remain refrigerated at all times.
Save The Onions: The pickled onions can be used on sandwiches, burgers, salads, and wraps after the eggs have been eaten.
