The Ancient Chili Sauce That Still Lives in Your Salsa

The chili sauce you dip your chips in has been around for a while!

Aztec and Maya populations were already pouring a similar sauce over their food before we even thought of chopping a tomato. This was a fiery chili sauce that many historians consider an early ancestor of modern Salsa.

Salsa’s story emerges from archaeology, colonial chronicles, and centuries of food traditions.

Dating back at least 2,000–3,000 years, the earliest known spicy dip was a chili pepper sauce developed by the ancient Mesoamerican civilizations. This ancient sauce, an ancestor of modern salsa, was made by crushing chili peppers, tomatoes, and ground seeds on stone tools and used as a dipping sauce for maize-based foods.

An All-American Sauce

Chili peppers were first used around 6,000 years ago, in present-day Mexico and parts of South America. They were a fixture of local cuisines a long time before global trade spread them worldwide.

Archaeologists studying Mesoamerican vessels found residue indicating that chili peppers were used as a condiment or sauce as early as 400 BCE. Some researchers believe these preparations were poured over food or mixed into drinks to add heat and flavor.

Residue found in ancient Mesoamerican vessels suggests that chili peppers were used as a sauce or condiment as far back as 400 BCE. Some experts believe that these chili-based preparations were either poured over food or incorporated into drinks to introduce flavor and heat.

In other words, today’s salsa may have been splashed onto meals more than two millennia ago.

What Did Ancient Salsa Taste Like?

Food historians believe the early sauces often combined several ingredients that are still used in salsa today:

• Chili peppers for heat
• Tomato for acidity and body
• Ground seeds or herbs for texture and flavor

In Aztec cuisine, sauces known as xilli or chilmolli were commonly eaten with maize-based foods such as tortillas and tamales. They were daily staples.

A 16th-Century Snapshot of Everyday Salsa

A 16th-century Spanish chronicler, Bernardino de Sahagún, gave us one of the clearest documented descriptions of Indigenous life in central Mexico after the Spanish conquest. He observed that people regularly ate meals accompanied by a variety of chili sauces, each with different ingredients and heat levels.

Back then, a bowl of chili sauce was an essential part of a meal.  

The Earliest Chili Condiments

Historians often describe Mesoamerican sauces as ancestors of salsa. But it’s important to understand that they are the earliest known chili-based condiments, not just ancient spicy sauce.

Other cultures also developed early condiments with heat or pungency, including:

• Mustard sauces in the Roman world
• Spice pastes in India
• Pepper and herb sauces around the Mediterranean

But what makes Mesoamerican sauces distinctive is the use of chili peppers as the central ingredient. This culinary tradition eventually spread around the globe after the great ecological transformation

The Ancient Roots of a Modern Favorite

Today, salsa appears in everything! From fresh pico de gallo to delicious smoky roasted varieties.

And the basic concept remains surprisingly similar to those early sauces:

• Chiles for heat
• Tomatoes or vegetables for balance
• Ground ingredients for depth
