Read first Safe temperature depends on species, cut, preparation and local guidance. Prevent cross-contamination, thaw safely, and use an instant-read thermometer. Sourcing and waste choices also affect the footprint.
How to use this guide Shop by method Tell the butcher the dish, heat level and cooking time, then confirm trim and weight.Cut across the grain Rest cooked meat, find the fiber direction and slice across it with a sharp knife.Expert voices A useful substitute matches muscle use, connective tissue and fat, not just price or color. Working butcher — Cut selection Quick answers Why does the same cut have several names? Countries divide carcasses differently, while retailers also use regional and marketing names.
Does searing seal in juices? No. Searing builds flavor and color; moisture retention depends more on final temperature, time and resting.
Key data Safety point Practical check Temperature Follow current local authority guidance for the species and preparation. Storage Keep cold, separate raw foods and label dates.

Local systems
IMPS/NAMP US institutional cut codes; retail names still diverge at the case.
EU carcass EU cutting lines and class stamps; shop labels are local vernacular.
Compare abroad Hanwoo grades and Wagyu BMS are reference systems — map anatomy first. Local examples Ask for trim weight and cooking method at the counter. Holiday rails: galbi sets, osechi/roast, asado cuts. Offal aliases connect gopchang, chitterlings and andouillette by tissue, not translation. Local FAQ Why does my recipe cut not match the supermarket label? Countries cut carcasses differently and retailers add marketing names — match by anatomy and cooking behavior.
Which doneness word should I use at the counter? Use the local vernacular and confirm internal temperature guidance.
Language note Localized meat URLs must keep navigation, labels and CTAs in the page language — no English chrome on /meat/ko/ or peers.
