• Chef’s knife

Ingredients

• 2 lbs Yukon Gold potatoes (about 6-8 medium potatoes), scrubbed
• 1 cup queso fresco, crumbled (or feta as a substitute)
• 2-3 whole fresh aji amarillo peppers, seeded and deveined (or 1/4 cup aji amarillo paste)
• 1/2 small yellow onion, roughly chopped
• 2 cloves garlic, peeled
• 1 can (12 oz) evaporated milk
• 4-6 saltine crackers
• 2 tablespoons vegetable or canola oil
• 1/2 teaspoon salt, or to taste
• 1/4 teaspoon black pepper
• For Garnish:
• 3 hard-boiled eggs, peeled and quartered
• 1/2 cup Kalamata or Peruvian botija olives
• 8-10 large lettuce leaves (like butter or romaine)

Instructions

1. Prepare the Potatoes and Eggs: Place the scrubbed potatoes and eggs in a large pot. Cover with cold, salted water by at least an inch. Bring to a boil over high heat. Once boiling, reduce heat to a simmer. Cook the eggs for 10 minutes, then carefully remove them with a slotted spoon and place them in an ice bath to cool. Continue to cook the potatoes until they are tender when pierced with a fork, about 20-25 minutes total. Drain the potatoes and set them aside to cool slightly.
2. Start the Sauce Base: While the potatoes are cooking, heat the 2 tablespoons of oil in a small skillet over medium heat. Add the chopped onion and garlic. Sauté for 5-7 minutes, until the onion is translucent and softened. If using fresh aji amarillo peppers, add them to the skillet for the last 2 minutes of cooking to soften them.
3. Blend the Sauce: Transfer the sautéed onion, garlic, and peppers to a high-speed blender. Add the crumbled queso fresco, 1 cup of the evaporated milk, the saltine crackers, salt, and pepper. If using aji amarillo paste, add it now. Blend on high speed until the sauce is completely smooth and creamy. This may take 1-2 minutes.
4. Adjust Consistency and Flavor: Check the sauce’s consistency. If it’s too thick, add more evaporated milk, one tablespoon at a time, until it reaches a pourable, gravy-like consistency. Taste the sauce and adjust the seasoning. Add more salt if needed, or a little more aji amarillo paste for extra heat and flavor. The crackers and cheese are salty, so be sure to taste before adding more salt.
5. Assemble the Dish: Once the potatoes are cool enough to handle, peel them (if desired, though Yukon Gold skins are thin and can be left on) and slice them into 1/2-inch thick rounds. Arrange the lettuce leaves on a large serving platter to create a bed. Place the sliced potatoes over the lettuce.
6. Serve: Generously pour the Huancaína sauce over the potatoes, ensuring each slice is well-coated. Garnish the platter with the quartered hard-boiled eggs and the olives. Serve immediately at room temperature or slightly chilled.

Expert Cooking Tips

• Choosing Potatoes: Waxy potatoes like Yukon Gold or red potatoes are ideal because they hold their shape well after boiling. Starchy potatoes like Russets are more likely to fall apart.
• Control the Heat: The seeds and veins of the aji amarillo peppers contain most of the heat. For a milder sauce, be sure to remove them thoroughly. For more spice, leave a few seeds in or add more paste.
• Achieving a Silky Sauce: For the smoothest possible sauce, blend for at least a full minute. If the sauce ‘breaks’ or looks grainy, it may be due to the cheese. Blending in a tablespoon of oil can sometimes help emulsify it back together.
• Sauce Consistency is Key: The sauce will thicken as it cools due to the crackers. Aim for a slightly thinner consistency than you want the final product to be. If it becomes too thick upon standing, you can whisk in a little more milk before serving.

Substitutions and Variations

Queso Fresco: If you can’t find queso fresco, a good quality feta cheese is the best substitute, though you may need to reduce the added salt. You can also use a blend of Muenster and cream cheese. Aji Amarillo: Aji amarillo paste is widely available in Latin American markets or online and is the easiest option. If you can’t find it, you cannot truly replicate the flavor, but you can approximate the color and heat by blending 1/2 an orange bell pepper (for color and sweetness) with 1/2 a habanero pepper (for heat). Saltine Crackers: The crackers act as a thickener. You can substitute with two slices of white bread with the crusts removed.

Common Mistakes to Avoid

Overcooking the Potatoes: Mushy, waterlogged potatoes will not hold their shape and will result in a messy dish. Boil them just until fork-tender. Sauce is Too Thin or Thick: A common issue is not balancing the milk and crackers. Start with less milk and fewer crackers than you think you need, and add more of each as you blend to achieve the perfect consistency. Forgetting to Taste: The saltiness of queso fresco and crackers can vary wildly by brand. It is crucial to taste the sauce before serving and adjust the salt level accordingly.

Serving Suggestions

Papa a la Huancaína is traditionally served as an appetizer or first course. However, the versatile sauce is fantastic served over grilled chicken breasts, steak, or even used as a creamy pasta sauce (known in Peru as ‘Tallarines a la Huancaína’). It also makes an excellent, unique dip for tortilla chips, french fries, or raw vegetables.

Storage and Reheating Tips

Store the Huancaína sauce and the cooked potatoes in separate airtight containers in the refrigerator for up to 3 days. The sauce will thicken considerably when chilled; let it sit at room temperature for 30 minutes or gently warm it, whisking in a splash of milk to loosen it before serving. Do not freeze the sauce, as the dairy will separate upon thawing.

Frequently Asked Questions

What is aji amarillo and is it very spicy?

Aji amarillo, or ‘yellow chili pepper,’ is a staple in Peruvian cooking. It has a unique fruity, berry-like flavor with a medium heat level, similar to a serrano or cayenne pepper. Most of the heat is in the seeds and veins, which are typically removed.

Where can I buy aji amarillo paste?

You can find aji amarillo paste in most Latin American grocery stores, in the international aisle of well-stocked supermarkets, or easily online from various retailers.

Can I make this recipe vegan?

Making a vegan version is challenging due to the dairy base. However, you can try substituting the queso fresco with a firm, salty vegan cheese (like vegan feta) and the evaporated milk with an unsweetened, full-fat plant-based milk like cashew or soy milk. The flavor profile will be different but can still be delicious.

Can I make the sauce ahead of time?

Yes, absolutely. The sauce can be made up to 3 days in advance and stored in an airtight container in the refrigerator. The flavors will meld and may even improve overnight. Just remember to adjust the consistency with a little milk before serving, as it will thicken.
