Cooking a steak
 

I read somewhere, that before you cook a steak on the grille, you should cover both sides with mustard, instead of marinating it. Has anyone done that?

Never ever! I do worcestershire followed by a dry rub and garlic.

Well, it is April Fools Day.

Followed with throw in garbage

Well if you google it it's not unheard of and worth a try

It was a serious post, albeit April 1

might be a steak strindberg 4 minute steaks (sometimes also known as cube steaks, thin cuts of red meat)
4 Tablespoons mustard
1 finely chopped onion
2 egg yolks
Mix mustard and egg yolks to a batter, spread it on one side of the steak and drizzle chopped onion on top. Put the steak in the frying pan batter side up, turn the steak once. Serve the steaks with fried or boiled potatoes.

If you go to the trouble of buying a good steak, why in the world would you do anything to it except salt and pepper? If you buy a cheap cut, then yeah...marinade.

I sprinke sugar on both sides and let sit for 10 minutes to melt. Then I put on a Hot grille for 30 seconds then flip over. This caramelizes the sugar and this in turn seals in the juices!! Try it!!

I think the mustard is to hold any rub on the meat no flavor from mustard just to make other goodies to stick to meat

I have never marinated a steak with mustard but when I think about it when you make Steak Diane mustard is a key ingredient. If you do try it please share how it is.

Never marinate a good Prime steak, get your grill as hot as it can get--we can get ours close to 1000 degrees-sear each side 1-1/2 minutes--remove steak-throttle grill down to 450, cover the steak with butter, when internal reaches 110, remove cover & let rest for 5 minutes--steak should be @ least 1.75 " thick, the marbling in a Prime steak , gives all the flavor you need---no seasoning ever-prefer a rib-eye

I like to use oil garlic and rosemary

We had this in Duesseldorf Germany. It was very good

No garlic?????
