Marinade for Flank steak

I try to prep meat the day before I plan on using it so that it has time to marinate and add more flavor to the dish. I am having flank steak tomorrow so I started the marinade today. Here is the recipe for the marinade that I am using. (my creation :)

Marinade for Flank Steak

1/4 cup olive oil

1/4 cup balsamic vinegar

3 tbsp orange marmalade

3/4 tsp dried thyme

3/4 tsp celery salt

1/4 tsp ground ginger

1 tbsp minced garlic

I am allowing to marinade overnight. but even 2 hours would be good. I am hoping to grill tomorrow, if it's not raining, if not I will broil this and then slice. Cooking it medium rare. light warm pink in the middle. about 10 min on each side under the broiler.

I will be serving this on top of a salad. Enjoy :) I will post pictures soon:)
