The Venezuelan avocado-based sauce listed as similar to guacamole is guasacaca.
Guasacaca is a savory sauce associated especially with Venezuela, where recipes commonly combine avocado with vinegar or lime juice, herbs, onions, peppers, garlic, and oil. Compared with guacamole, it is often thinner and more acidic, although its texture varies from smooth to chunky.
The two preparations are related but not interchangeable in every culinary context. Guacamole is strongly associated with Mexican cuisine and is commonly served as a dip, spread, or accompaniment, while Venezuelan guasacaca is frequently spooned over grilled meats, arepas, empanadas, and other dishes. Some Venezuelan versions even omit avocado, so the name does not always guarantee the same ingredients.
A common mix-up is chimichurri, another green sauce served with grilled foods. Venezuelan guasacaca may resemble chimichurri in color and use, but Wikipedia specifically identifies guasacaca—not chimichurri—as the Venezuelan sauce similar to guacamole.
