This place just north of Boston has won a ton of awards for their steak tips and secret marinade.
NewBridge Cafe | 650 Washington Ave. Chelsea, MA 02150
Use to go there all the time when we lived back east. About 10 years ago during a trip back there I got the owner to give me his marinade recipe since I was living out on the west coast now.
You wanna mix this together real good and let your steak tips (works really good with chicken too) marinade in the sauce for at least 8 hours before grilling them.
1/2 cup good quality ketchup
2 tablespoons sugar
2 tablespoons vinegar
2 tablespoons worchestshire sauce
2 teaspoons olive oil
1/2 teaspoon salt
1/2 teaspoon dried finely crushed tarragon (crush the dried flakes into a powder with your fingers)
1/4 teaspoon garlic powder
