Why is Chimichurri Level 3 on average?
Chimichurri is one of the simplest and least processed condiments in any cuisine. The preparation involves finely chopping flat-leaf parsley, mincing garlic, mixing with dried oregano and red pepper flakes, then combining with red wine vinegar and olive oil. The entire process is mechanical; chopping and mixing. No heat is applied, no emulsification is required, and no preservatives are needed because the vinegar and oil naturally preserve it for 1-2 weeks refrigerated. The sauce is traditionally served fresh alongside grilled meats in Argentina and Uruguay. Unlike almost every other commercial condiment, chimichurri's very nature resists industrial processing, and the fresh herb flavor degrades quickly when preserved, which is why most chimichurri available in stores is refrigerated with a short shelf life, or it has been modified with preservatives and stabilizers that compromise its character. In our analysis, packaged chimichurri products average a Processing Score of 5.6, which is Level 3.

Frequently asked questions
What is chimichurri?

How long does chimichurri last?
Homemade chimichurri lasts 1-2 weeks refrigerated. The vinegar and olive oil act as natural preservatives. The flavor actually improves after a few hours as the herbs infuse into the oil and vinegar.
Is chimichurri the same as salsa verde?
No. Chimichurri (Argentine) is parsley-based with oregano and vinegar. Italian salsa verde is similar but adds capers and anchovies. Mexican salsa verde is tomatillo-based. Made fresh, all three are minimally processed but use different ingredients and traditions.
