- Ground turmeric (1 tsp): Delivers vibrant color and earthy notes.
- Celery seed (1 tsp): Adds depth and a subtle herbal hint.

Timing
Let’s talk timing because who wants to wait forever for a good pickle?
- Prep Time: 20 minutes
- Pickling Time: 1 hour (for quick pickles)
- Total Time: 1 hour 20 minutes
That’s about 20% less time than many traditional cucumber-based pickle recipes, which means more snack time and less waiting!
Step-by-Step Instructions
Step 1: Salt and Sweat
Place sliced zucchini and onion in a colander. Sprinkle with coarse salt, toss gently, and let them “sweat” for 1 hour. This pulls out excess moisture, giving you crunchier pickles.
Tip: Placing a plate with a weight on top helps speed up the process!
Step 2: Rinse and Drain
After an hour, rinse your veggies thoroughly under cold water to remove excess salt. Pat them dry seriously, go for that paper towel action! You want as little moisture as possible.
Step 3: Prepare the Brine
In a large saucepan, combine white vinegar, sugar, mustard seeds, mustard powder, turmeric, celery seed, and black peppercorns. Bring to a simmer over medium heat, stirring to dissolve the sugar and infuse those spices.
Pro Tip: Letting the brine simmer for a few minutes draws out all those flavors.
Step 4: Combine and Pack
Add the zucchini and onions to the brine, stirring gently. Simmer for 2–3 minutes just enough to heat through but not so long they lose their snap. Pack veggies and brine into sterilized jars.
Tip: Use a funnel for spill-proof packing!
Step 5: Cool and Pickle
Seal the jars and let them cool to room temperature. For best results, refrigerate for at least 24 hours…if you can wait that long. (We won’t judge if you sneak a taste early.)
