I grilled some pork loin for dinner.
Let's make steak with sirloin tonight.
The pork loin cutlet at this restaurant is tender and delicious.
I sliced the loin thinly for shabu-shabu.
ロース is the broader loin category of meat, while サーロイン refers specifically to the well-marbled cut at the rear of the loin.
Sliced ロース is typically counted with 枚, as in ロース肉２枚 for two slices of loin meat.
rib roast
loin ham; ham made from pork loin
beef loin; beef sirloin; beef roast
shoulder roast
pork loin; pork roast
Borrowed from English 'roast', but in Japanese it specifically refers to the loin cut of meat rather than the cooking method.
