Pickled Cauliflower With Red Onion: A Culinary Gem

There’s something magical about the alchemy of pickling. I remember the first time I helped my grandmother make pickled vegetables. The air filled with the tangy scent of vinegar and spices, and the vibrant colors of the produce seemed to glow within their jars. We carefully layered crisp cucumbers, crunchy carrots, and firm cauliflower, each destined to become a delicious, tangy treat. Even now, decades later, the simple act of pickling brings back a flood of warm memories and the comforting feeling of home. This pickled cauliflower and red onion recipe is a delightful homage to those cherished moments, offering a bright and flavorful bite that’s perfect on its own or as part of a larger spread.

Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 10 minutes
• Total Time: 30 minutes (plus overnight refrigeration)
• Yields: 1 quart
• Dietary Type: Vegan, Gluten-Free

Ingredients

• 1/2 head cauliflower, cut into florets
• 1 red onion, sliced thin into 1/4-inch slices
• 1 garlic clove, thinly sliced
• 3/4 cup red wine vinegar
• 3/4 cup distilled white vinegar
• 3/4 cup water
• 2 tablespoons sugar
• Kosher salt
• 1 teaspoon coriander seed
• Lemon zest (1 wide strip)

Equipment Needed

• Medium pot
• Colander
• Quart jar
• Small saucepan

Instructions

1. Begin by preparing the cauliflower. Bring a medium pot of water to a boil. Once boiling, add the cauliflower florets and blanch them until they are tender-crisp, approximately 2 minutes.

2. Immediately drain the blanched cauliflower and rinse it under cold water to stop the cooking process and cool it off completely. This step is crucial to maintaining a desirable texture.

3. Next, it’s time to pack the jar. Into a clean quart jar, carefully layer the cauliflower florets, thinly sliced red onion, and thinly sliced garlic clove. Distribute the ingredients evenly throughout the jar.

4. Now, prepare the brine. In a small saucepan, combine the red wine vinegar, distilled white vinegar, water, sugar, 1 1/2 teaspoons of kosher salt, coriander seeds, and the strip of lemon zest.

5. Bring the brine to a boil over medium heat, stirring occasionally to ensure the sugar and salt dissolve completely. Once boiling, remove the saucepan from the heat.

6. Carefully pour the hot brine over the cauliflower and onion mixture in the jar, ensuring that all the vegetables are submerged. If necessary, gently press down on the vegetables to release any trapped air and ensure they are covered in brine.

7. Let the jar cool to room temperature. This allows the flavors to begin melding and the vegetables to start absorbing the brine.

8. Once cooled, cover the jar tightly and refrigerate it overnight, or for up to 1 week. The longer it sits, the more flavorful it becomes.

Expert Tips & Tricks

• Brine Strength is Key: Don’t be afraid to adjust the sugar or salt in the brine to your liking. Taste it before you pour it over the vegetables, and adjust accordingly. Remember that the flavor will intensify as it sits.
• Spice it Up: For a touch of heat, add a pinch of red pepper flakes to the brine.
• Don’t Overcook the Cauliflower: The cauliflower should be tender-crisp, not mushy. Overcooked cauliflower will lose its appealing texture in the pickling process.
• Even Slicing Matters: Uniformly sliced red onion ensures even pickling and a more consistent flavor throughout the jar. A mandoline can be helpful here.
• Lemon Zest Matters: Use a vegetable peeler to take a wide strip of lemon zest – avoid the white pith, which is bitter.
• Sterilize the Jar: While not strictly necessary if you plan to eat the pickled cauliflower within a week, sterilizing the jar and lid will extend its shelf life.

Serving & Storage Suggestions

This pickled cauliflower with red onion is incredibly versatile. Serve it chilled as a bright and tangy side dish, as part of an antipasti platter with meats and cheeses, or as a crunchy topping for salads and sandwiches.

Store the pickled cauliflower in the refrigerator in its brine for up to 1 week. Be sure to use a clean utensil each time you remove some from the jar to prevent contamination. This pickle is best enjoyed cold, straight from the fridge. This recipe isn’t recommended for long-term canning due to not following proper canning procedures, so make it to eat within the week!
