Cold sauces & condiments
Guacamole
Aguacate molido · A cold, uncooked sauce and condiment originating from pre-Columbian Mesoamerica, made by mashing ripe avocado with citrus acid, aromatics, and seasonings. It is both a dip and a foundational flavor component that balances rich, buttery fat with bright acidity and herbal freshness. The texture should be rough and uneven — not smooth — with visible heterogeneity.
The formula
3 parts avocado : 1 part citrus juice (by weight), plus ~15% aromatics by total weight
One medium Hass avocado (~150g flesh) needs ~50g (2–3 tbsp) fresh lime juice. Aromatics (onion, cilantro, chili) total ~20–25g. Salt to 1.5–2% of total weight. Scale by the avocado count, not by feel.
Identity
- Ripe Hass avocado — black, yielding to gentle pressure; never underripe or stringy
- Fresh lime juice — freshly squeezed, never bottled concentrate
- Rough, uneven texture — mash with a fork or knife, never puree
- No heat applied — it is a cold sauce, always
- Seasoned properly at the end — salt amplifies everything, add last and taste twice
Ingredients
| Base | Hass avocado | Black-skinned, yielding. 1 medium = ~150g usable flesh. Fuerte or other green varieties acceptable but less creamy. |
| Acid | Fresh lime juice | Mexican limes (Key limes) or Persian. 2–3 tbsp per avocado. Citrus acid slows enzymatic browning and brightens flavor. |
| Aromatics | White or red onion, finely diced | Finely brunoise (3mm). Soak in cold water 5 min to tame harshness, then drain well. Red onion is acceptable in Northern Mexican styles. |
| Aromatics | Fresh cilantro (coriander leaves) | Leaves and tender top stems only. Rough-chopped. Classical Mexican: always included. Northern styles may omit. |
| Seasoning | Serrano or jalapeño chili | Seeded and minced for moderate heat. Serranos are traditional in central Mexico. Use to taste; optional in very traditional preparations. |
| Seasoning | Kosher or fine sea salt | 2% of total batch weight. Diamond Crystal kosher (~1 tsp per 3 avocados). Never omit — salt is not optional. |
| Seasoning | Cumin (optional, Tex-Mex only) | A pinch, used only in Tex-Mex or Southwestern variations. Not classical. |
Method
- 1Halve and pit the avocados, then scoop flesh into a wide, non-reactive bowl.A wide bowl allows working with a fork without forcing avocado against the sides. Stainless steel or glass is preferred over reactive metal.
- 2Add lime juice immediately over the flesh before mashing.Citric acid lowers pH and inhibits polyphenol oxidase, the enzyme responsible for browning. This also begins seasoning the fat itself.
- 3Mash the avocado with a fork or the edge of a tablespoon — leave it rough, uneven, and chunky.Textural integrity is non-negotiable. Smoothing it in a food processor ruptures cells uniformly, accelerating oxidation and producing a dull, gluey result.
- 4Fold in the drained onion, cilantro, and minced chili. Add salt.Aromatics are folded (not stirred) to preserve texture. Salt is added last and tasted; it amplifies all flavors and should be adjusted after everything is combined.
- 5Taste and correct acid, salt, and heat. Press plastic wrap directly onto the surface, cover, and chill 15–30 minutes before serving.Resting allows flavors to marry. The plastic barrier minimizes air exposure, slowing oxidation. Do not skip the press.
Techniques that matter
Rough mashing (not pureeing)
Preserves cell wall integrity and uneven texture. A fork or bench knife held at an angle gives the correct irregular cut.
Immediate acid addition
Citric and ascorbic acids in lime juice denature the oxidative enzymes in avocado flesh. Delay allows rapid browning.
Pressing and covering
Minimizes surface area exposed to oxygen. For service, top with an extra lime wedge and serve immediately.
Tasting and seasoning in layers
Acid, then salt, then heat — each element must be assessed independently. The lime should be perceptible but not dominant; salt at ~2% of total weight.
Variations & derivatives
Guacamole tradicional (central Mexico)Mexico City, central states
Onion, cilantro, serrano, lime, salt. No tomato, no cumin. The reference standard.
Guacamole de frontera (Northern Mexico)Baja California, Sonora
Often includes diced tomato and omits cilantro. Thicker, chunkier consistency.
Guacamole with roasted tomato and pepitaPuebla, Veracruz
Roasted tomate rojo, pepitas (pumpkin seeds), epazote. A heartier, more complex regional form.
Guacamole enfundado (stuffed)Mexico
Made inside a carved avocado shell or as a stuffed pepper. Decorative but legitimate.
Guacamole with baconUnited States (Tex-Mex, Texan-style)
Crisp bacon crumbled in. Not classical but broadly used in American contexts. Adds rendered fat and smoky salt.
Guacamole with mango or pineappleCoastal Mexico, Central America
Diced tropical fruit added. Found in Yucatán and Central American coastal preparations for sweet-hot contrast.

Substitutions
- Fresh lime juice → Fresh lemon juice — Acceptable in emergencies; lemon is less acidic and more neutral. Mexican limes are preferred for authentic brightness.
- Fresh lime juice → Bottled lime juice — Acceptable in commercial contexts; significantly less bright, more flat. Some bottled lime juice contains preservatives that affect flavor.
- Hass avocado → Fuerte or other green-skin avocado varieties — Fuerte has slightly higher water content and less creaminess. Adjust lime accordingly.
- White onion → Shallot — Milder, more delicate. Soak in water as you would white onion. Common in refined preparations.
- Serrano chili → Cayenne powder — Use at ~1/4 tsp per avocado to approximate medium heat. Adjust to taste.changes result
- Cilantro → Flat-leaf parsley — Acceptable for those who find cilantro soapy. Produces a different, more neutral herb flavor. Common in non-Mexican commercial preparations.changes result
Troubleshooting
Rapid browning (within 15–30 minutes of preparation)
Insufficient lime juice, delayed acid addition, or avocados were overripe and already oxidizing before preparation. Using a dull knife that crushes cells rather than cuts them also accelerates browning. → Use more lime juice — the ratio should be unmistakable in the flavor. Add lime the moment the avocado is cut. If already made, sprinkle an additional tablespoon of lime juice, press plastic flush to the surface, and use immediately. Consider a pinch of ascorbic acid powder (vitamin C) as an anti-oxidant if preparing for service.
Watery or runny consistency
Avocados were underripe and releasing liquid as they continue to ripen after mashing. Over-mashing ruptures cell walls completely, releasing intracellular water. → Use only fully ripe avocados. If slightly underripe, let ripen at room temperature 12–24 hours more. If the batch is already watery, drain excess liquid and fold in a small amount of very ripe, firm avocado to rethicken.
Flat, muted flavor despite proper seasoning
Salt may be adequately present but under tasted due to palate fatigue. Avocados were refrigerated too cold, numbing volatile compounds. Lime may need adjustment. → Ensure the guacamole is tasted after a brief 5-minute rest. Use slightly warmer-than-fridge temperature for service. Use proper technique: taste, adjust, rest, taste again.
