Chilean Onion Relish: A Vibrant Taste of South America

I remember the first time I tasted a true Chilean onion relish. It wasn’t in a restaurant, but at a small family barbecue during my travels through the Andes. The smoky aroma of the asado filled the air, and this vibrant, tangy relish, generously spooned over grilled chorizo, was an explosion of fresh flavors that perfectly cut through the richness of the meat. The bright red of the tomatoes, the sharpness of the onions, and the herbaceous cilantro – it was a culinary awakening I’ll never forget, a testament to the power of simple, fresh ingredients transformed into something truly special.

Recipe Overview

• Prep Time: 35 minutes
• Cook Time: 0 minutes (standing time)
• Total Time: 35 minutes (plus a few hours standing time)
• Servings: 4
• Yields: 2 cups
• Dietary Type: Vegan

Ingredients

• 1 medium onion, cut into very fine dice
• Ice water, for soaking the onions
• ¼ cup red wine vinegar (to taste) or ¼ cup distilled vinegar (to taste)
• 1 teaspoon coarse kosher salt (to taste) or 1 teaspoon sea salt (to taste)
• 1 large tomato, it doesn’t need to be too ripe, seeded, and very finely diced
• ½ teaspoon fresh ground black pepper
• ¼ teaspoon cayenne pepper (to taste)
• 2 tablespoons vegetable oil
• ¼ cup chopped fresh cilantro or ¼ cup chopped flat leaf parsley

Equipment Needed

• Large bowl
• Colander
• Paper towels
• Small bowl
• Whisk or fork

Instructions

1. Begin by preparing the onion. Finely dice the onion and place it in a large bowl.

2. Cover the diced onion completely with ice water. This step is crucial as it mellows the onion’s harshness, creating a milder, more palatable flavor for the relish.

3. Let the onion stand in the ice water for 30 minutes. This allows the water to draw out the pungent compounds.

4. After 30 minutes, drain the onion well in a colander. Ensure as much water as possible is removed.

5. Using paper towels, thoroughly blot the drained onion dry. This step prevents the relish from becoming watery.

6. In a separate small bowl, combine the red wine vinegar (or distilled vinegar) and the salt.

7. Stir or whisk the vinegar and salt together until the salt crystals are completely dissolved. This creates a flavorful base for the relish.

8. Add the dried onion, diced tomato, black pepper, cayenne pepper, and vegetable oil to the bowl with the vinegar mixture.

9. Add the chopped cilantro (or flat leaf parsley) to the bowl.

10. Gently toss all the ingredients together until they are well combined. Be careful not to crush the tomato.

11. Taste the relish and correct the seasoning. Add more salt, vinegar, or cayenne pepper as needed to achieve the desired flavor balance. Remember that the relish should be highly seasoned to complement grilled meats or other dishes.

12. Although the relish is good to eat immediately, it will be even better if you allow it to stand to ripen for a few hours before serving. This allows the flavors to meld and deepen.

13. Serve the relish the same day it is made for the best flavor and texture. This recipe yields about 2 cups, enough to serve 4 to 6 people.

Expert Tips & Tricks

• Spice It Up: For an extra kick, add a finely minced jalapeño or a dash of hot sauce to the relish.
• Herb Variations: While cilantro is traditional, parsley, mint, or even a combination of herbs can be used for a different flavor profile.
• Make-Ahead: You can prepare the relish a few hours in advance and store it in the refrigerator. However, keep in mind that the tomatoes may release some liquid over time.
• Onion Choice: While a regular yellow or white onion works well, using a slightly sweeter variety like Vidalia or red onion can add another layer of complexity.
• Tomato Ripeness: Using a firm but ripe tomato prevents the relish from becoming too mushy.
• Salt Matters: Always taste and adjust salt. The correct amount will bring out the sweetness of the tomatoes and the depth of flavor.

Serving & Storage Suggestions

This Chilean onion relish is traditionally served with grilled meats, especially beef, pork, and sausages. It’s also fantastic with grilled chicken or fish. Beyond meat, it can be used as a topping for bruschetta, tacos, or even stirred into scrambled eggs.

For storage, the relish is best served the same day it’s made. If you have leftovers, store them in an airtight container in the refrigerator for up to 24 hours. The relish will release liquid as it sits, so drain off any excess liquid before serving. Due to the fresh ingredients, it’s not recommended to freeze this relish.
