Which similar avocado dish means 'poor man's butter' in Spanish?

The similar avocado dish that means “poor man’s butter” in Spanish is Mantequilla de pobre.

The name refers to the dish’s buttery texture and avocado base, not to dairy butter. Mantequilla de pobre is described as a mixture of avocado, tomato, oil, and citrus juice. It belongs among the many avocado preparations that resemble guacamole without being the same dish.

A common mix-up is to choose a familiar Mexican salsa such as pico de gallo or salsa verde. Those are different preparations: pico de gallo is generally a fresh chopped salsa, while salsa verde is built around green ingredients such as tomatillos or green chiles. Mantequilla de pobre is defined by avocado as its central ingredient.

The phrase also has an interesting historical wrinkle. Despite the “butter substitute” implication of its name, the dish is said to predate the arrival of dairy cattle in the Americas, so it was not originally created as a replacement for cow’s butter. Guacamole itself developed in Mexico and has since become an international dip, spread, and salad ingredient.
