destazar

A culinary and butchery term meaning to cut up or butcher meat into pieces — destazar una res, to butcher a cow into cuts. It's standard vocabulary in slaughterhouses, butcher shops, and cooking, especially in Mexico; it also appears, more grimly, in Mexican crime reporting when describing dismembered remains, which has made the word carry heavier connotations in the news than in the kitchen.

• El carnicero destazó el pollo en varias piezas. — The butcher cut up the chicken into several pieces.
• En el rancho, destazan la res el mismo día del sacrificio. — On the ranch, they butcher the cow the same day it's slaughtered.
• El curso de cocina enseña a destazar distintos tipos de carne. — The cooking course teaches how to butcher different kinds of meat.

Assuming destazar is neutral in every context — in ordinary cooking it's a plain technical term, but Mexican readers will also associate it with grim crime-news headlines, so tone and context matter more than for a word like cortar.
