HELP... need teriyaki marinade for chicken

Teriyaki is very simple to make. equal parts of soy and worstershire, add splash of lemon juice. I sometimes add honey or hoisen to make it more thick and to make it more rich flavored. You can add a dash of hot sauce for a little heat. HTH

classic teriyaki is equal parts , mirin [japanese sweet rice wine for cooking] sake and soy. heated to drive of the alcohol from the sake. sugar can be substituted for the mirin. the used marniade can be brought to a simmer and thickened with corn starch. sesame seeds, garlic, black bean sauce, worcestershire, ginger and lemon can all be added per your taste. lemon and soy is particulary good on sea food and is comercially available as 'ponzu' sauce.
the soy vey products are great, their wasabiyaki is worth a look as well . careful with any commercial marinade, higher sugar content is likely to burn at high temps.
if you have an asian market. yakitori is great. chicken on skewers basted with yakitori sauce. i do these at lower temp turn and baste several times so it makes a glace with out burning and check frequently with thermo pen. i can take and post picks of all these products if you want a visual to help in your shopping.
