Mix all ingredients together and place steaks into freezer bag with marinade, preferably overnight.

Preheat oven to 325 degrees F. Cut 1/2 inch off the top of garlic head. Cut roots so that the garlic will sit flat. Remove papery skin, leaving enough so cloves stay together. In a small oven safe casserole dish, place garlic in dish and drizzle olive oil over it then cover with foil. Place in oven and allow to bake for 1 hour. Remove from oven and let cool until safe to touch. In a medium saucepan, combine water, soy sauce, teriyaki sauce, pineapple juice and brown sugar. Heat over medium/high heat, stirring occasionally until mixture boils then reduce heat until mixture is just simmering. In a small bowl, squeeze the sides of the head of garlic until the pasty roasted garlic is squeezed out. Measure 2 teaspoons into the saucepan and whisk. Add remaining ingredients to the pan and whisk to combine. Allow mixture to simmer for 40 to 50 minutes or until the sauce has reduced by 1/2 and is think and syrup like. Do not allow to boil over.
