WTF?!? Aloha Asia

Here's the recipe for the funky, festive meat dish featured on Friday from Better Homes & Gardens Cooking With Herbs and Spices (c)'67:

Flank Steak Teriyaki
1 recipe Ginger Marinade [stay tuned]
4 to 6 flank steak pinwheels [I guess the butcher has these all swirled and dizzy at the meat counter?]
4 to 6 pineapple slices

Pour Ginger Marinade over meat and marinate 1 to 1 1/2 hours [you thought I was going to say 4 to 6, didn't you?]. Broil 4 to 5 [gotcha!] inches from heat 7 minutes, brushing once with marinade. Turn and broil 5 to 7 minutes longer, brushing once with marinade. Add pineapple slices to boiler during last 3 to 4 minutes; brush with marinade [man, this is the groundhog's day of marinades]. Serve with rice.

Ginger Marinade
Combine 1 tablespoon salad oil, 1/2 cup soy sauce, 1/4 cup sugar, 2 tablespoons sherry [+ 1 for mama], 1 teaspoon ginger, 1 clove garlic (crushed), and 1/2 teaspoon monosodium glutamate [that delishy chemical combination of wtf ingredients created in a lab one night in the 40s].

This is one WTF?!? that sounds pretty Fing good! ;)
