Spicy Colombian aji delivers a zesty punch that transforms any dish from bland to brilliant. I reach for this salsa whenever grilled meats or arepas need a lively kick or when my friends gather for empanadas and crave something vibrant and fresh.
I learned about this fiery condiment from my Colombian roommate and now it brightens every taco night or backyard gathering. The vibrant colors and aromas pull people right to the table and it disappears fast.
Ingredients
- Hot pepper: Finely minced, choose your favorite for flavor and heat, look for glossy skin and firm flesh
- White vinegar: Provides brightness and helps preserve, buy a good quality vinegar for best taste
- Water: Ensures the salsa is not overly sharp, use filtered water if possible
- Salt: Enhances the natural flavors, use sea salt for a cleaner taste
- Sugar: Balances the tartness and heat, just a little goes a long way
- Lime juice: Freshens and adds a citrus kick, always use freshly squeezed
- Vegetable oil: Gives a silky finish, choose a neutral oil without strong flavor
- Fresh cilantro: Finely minced, brightens everything, buy bunches with deep green leaves, no wilting
- Scallions: Finely minced for sharp onion notes, select crisp white and green parts
- Tomato: Optional but adds sweetness and color, use ripe and juicy tomatoes
Step-by-Step Instructions
- Prepare the Vegetables:
- Finely mince your hot pepper, cilantro, scallions and tomato if using. Take your time here, the smaller the pieces the more flavor will infuse into the liquid.
- Mix the Base:
- Combine the minced veggies in a clean glass jar. Add the vinegar, water, salt, sugar, lime juice and vegetable oil. Stir thoroughly to distribute everything evenly.
- Adjust the Liquid:
- Check that the vegetables are just covered by the liquid. If you need more, add extra in a ratio of one part oil to two parts water to four parts vinegar. This ensures every bit marinates properly.
- Marinate the Salsa:
- Seal the jar tightly and let the mixture rest in a cool, dark area for at least twenty four hours. This deepens the flavors and allows everything to meld.
- Refrigerate and Serve:
- Move your aji to the fridge and keep chilled. Serve with your favorite Colombian or Latin dishes. The flavor will improve with time.

My favorite part is watching the color deepen after a day in the fridge. The cilantro and peppers almost look jewellike and my family cannot resist sneaking tastes every time they open the door. This sauce always brings us together even if it is just for a moment over the kitchen counter.
Storage Tips
Aji stores beautifully in a sealed glass jar in your refrigerator for up to ten days. Keep the veggies submerged in the liquid to maintain freshness. If you see the herbs losing their color, it is time for a new batch.
Ingredient Substitutions
If you want less heat, try green bell pepper for gentler flavor. Red onion can swap in for scallions for a sweeter taste. If cilantro is not your thing, flat leaf parsley is a solid backup. You can also use apple cider vinegar for a milder tang.
Serving Suggestions
Use this salsa as a topper for eggs or roasted vegetables. It is classic with grilled meats like churrasco or on warm arepas and empanadas. Sometimes we stir it into black beans for a sharp fresh bite.
Cultural and Historical Context
Aji is found throughout Colombia, with each region and family boasting their secret twist. Some add hard boiled eggs or more tomato, and in the Andean regions it is always on the table alongside hearty soups and stews. This versatile condiment reflects Colombian hospitality and love for sharing food at every meal.

I once rushed a batch for a party and realized that letting the aji sit overnight made all the difference in depth of flavor. Now I always plan ahead and it has become my secret weapon in any salsa lineup.
