The word 'teriyaki is a combination of two Japanese words, teri, "luster", and yaki, "to grill or broil". The mirin in the sauce gives a good lustre to meat as it is cooked. Traditionally it was used with fish. It can also be used as a marinade for pre-cooked meat and poultry, as well as a delicious baste for items on the grill or rotisserie. Teriyaki sauce is a complement to virtually any type of meat (as long as you adjust the flavors accordingly), especially steak, chicken, fish and pork.
