Step 1

To a blender, add the lime juice, olive oil, cheese, mayonnaise, serrano peppers, cilantro leaves, garlic cloves, green onions, huacatay paste, aji amarillo and salt. Blend for about 1 to 2 minutes, until very smooth. At first the cilantro leaves won't be totally smooth, but keep the blender running and it will eventually become cohesive and smooth.

Step 2

Give it a taste and adjust the salt according to your liking. Keeps in the fridge for up to a week.
