We have not used the shaker bottle, but we’ve used the same thing in the steak marinade packets several times. You mix it with some water, red wine vinegar, and olive oil, and marinate the steaks in it for about 30 minutes. It is very good!!

YES! It’s worth buying the big bottle. If you want to be blown away, try this:

Mix 1/2 cup of brown sugar with about 2 cups of soy sauce
Douse a “London Broil” (usually Round Steak, thickly cut) with that mixture.
salt & pepper, plus a liberal amount of the Montreal Steak Seasoning on both sides.

Let that percolate for a couple of hours (the longer the better, up to about 6-8 hours)

Grill it to your preferred temperature (I usually shoot for medium-well on this one). Slice it thinly, like a regular London Broil.

It’s as good as a London Broil can ever be.

Ed- thanks for the tip. We do a London broil every once in a while and I’d love to try out your suggestion.
