Citrus Herb Marinade
This is my favorite marinade for beef steaks. It's from the good old Joy of Cooking. You can assemble this in about 3 minutes. I like to marinate steaks for 8 hours or up to 2 days in this marinade. If pan cooking, I use some of the marinade to provide liquid to the pan.
1/4 c mild tasting oil (olive oil or sunflower work well here)
2.5 TB lemon juice
1.5 TB orange juice or red wine
1/3 c parsley (nice if you have it - but I often don't and just skip)
1.5 tsp dried thyme or appropriate herb
1/2 bay leaf crumbled
1 clove garlic, minced
1 tsp salt
1/4 tsp black pepper
