Sacha Sauce Recipe: Peruvian Aji Amarillo Creamy Blend

This Peruvian sauce brings vibrant, creamy heat to any dish. I developed this blend after tasting the original at a Lima food market.

The aji amarillo peppers create its signature golden color and fruity spice. With just a few ingredients and a blender, you’ll capture authentic flavor.

Ingredients for Sacha Sauce

A few bold ingredients blend into this golden, creamy Peruvian sauce with serious kick.

Aji amarillo peppers are non-negotiable here. Latin markets often carry fresh ones, but jarred (from Inca’s Food or Melissa’s) works in a pinch—just drain them well. The peppers should be bright yellow-orange, not dull. Mayonnaise is the base, so go for Duke’s or Hellmann’s (the full-fat kind) for that ultra-creamy texture. Skip the light stuff; it’ll separate.

No aji amarillo? Habanero plus a pinch of turmeric for color gets you close, though the flavor won’t be the same. Out of lime juice? White vinegar at half the amount plus a squeeze of lemon works. Want it spicier? Add a dash of cayenne. The mustard can be swapped for Dijon if you want a sharper bite, but yellow keeps it classic.

This keeps for about 2 weeks in the fridge—store in a clean jar. The oil might separate, so give it a stir before using. Freeze in ice cube trays for up to 3 months if you won’t use it fast.

Step-by-Step Instructions for Sacha Sauce

Here’s the method. Straightforward, tested, works every time.

Step 1: Prepare the Aji Amarillo Peppers

Start by removing the stems from all 6 whole Aji Amarillo Peppers. If you’re using fresh peppers, give them a quick rinse to remove any dirt. I’ve found that jarred peppers work just as well here, and they save you the hassle of tracking down fresh ones.

If the peppers are large, I rough chop them into a few pieces so they blend more easily. There’s no need to remove the seeds unless you prefer a milder flavor—keeping them in adds a little extra heat and authenticity to the sauce.

Step 2: Blend the Base Ingredients

In a blender or food processor, combine the prepared 6 whole Aji Amarillo Peppers, 0.75 cup Mayonnaise, 0.25 cup Vegetable Oil, and 3 cloves Garlic Cloves. Pulse until the mixture is smooth and creamy. You might need to stop and scrape down the sides a couple of times to ensure everything gets incorporated.

This is where the magic starts happening—the aji amarillo peppers give the sauce its signature vibrant yellow color and fruity, slightly spicy flavor, while the mayonnaise creates that rich, creamy base we’re after.

Step 3: Add the Finishing Touches

Now, add the 2 tbsp Lime Juice, 0.5 tsp Salt, 1 tbsp White Vinegar, and 1 tsp Yellow Mustard to the blender. Pulse again until everything is fully combined and the sauce looks uniform. Taste and adjust the seasoning if needed—I sometimes add a pinch more salt if the flavors seem a bit flat.

The lime juice and white vinegar brighten up the sauce and balance the richness of the mayonnaise, while the yellow mustard adds a subtle tangy depth. Real talk: this is the moment that matters.

Step 4: Chill and Let the Flavors Meld

Transfer the sauce to a jar or airtight container and refrigerate for at least 30 minutes. This resting time allows the flavors to meld together and deepen. I know it’s hard to wait when it smells this good, but it’s worth it.

Here’s the thing—the sauce will thicken slightly as it chills, and the garlic and aji amarillo flavors will mellow and harmonize. If it seems too thick after chilling, you can thin it out with a little water or additional lime juice to reach your desired consistency.

Storing and Reheating This Recipe

Fridge Storage

Transfer your sauce to a clean glass jar with a tight lid. It keeps beautifully in the fridge for up to 2 weeks. I recommend using a 16-ounce mason jar for the perfect fit. The oil might separate naturally, but a quick stir brings it back to life. ❄️

Freezing for Later

For long-term storage, freeze in ice cube trays for 1-2 hours, then transfer to a freezer bag. This method lets you portion out exactly what you need. It stays fresh for up to 3 months without losing its vibrant flavor.

Thawing Tips

Move frozen cubes to the fridge overnight for gradual thawing. If you’re in a hurry, place the jar in a bowl of cold water and change the water every 30 minutes. Never microwave directly from frozen—it can cause separation.

Reviving Separated Sauce

If your sauce separates after storage, don’t worry. Just let it sit at room temperature for 10-15 minutes, then whisk vigorously. Add 1 tsp lime juice if needed to restore its creamy consistency. 💡

Room Temperature Use

Always return unused portions to the fridge within 2 hours. This sauce doesn’t contain preservatives, so it’s best to keep it cold when not in use. I’ve found it tastes best when slightly chilled rather than at room temperature.

Storage Check

Before using stored sauce, give it a quick sniff. If it smells off or you see any mold, it’s best to discard it. The bright yellow color should remain vibrant—any dulling might indicate it’s past its prime.
