how much teriyaki sauce to add to burgers?

I’m planning on making some teriyaki burgers later with Soy Vay sauce - a mix of soy, ginger, etc. - basically a thick teriyaki sauce.

How much should I toss into a pound of hamburger meat? Half a cup? A tablespoon?

About 4 table spoons will do ya. More will make the mixture too wet and salty.

As a suggestion, lot’s of fresh garlic (minced), dry onion flakes and dash or two of red chilli pepper flakes.

Bon Appetite!

It depends on how teri you like your yaki.
