Chef explores the best way to eat beefsteak

Today we are making stake frites with beef halal.
Please note that the French call it bavette, which means "halami steak," and it is damn tasty.
This time, I prepped the part of the jalami called sagari from a chunk of meat, but you can make this recipe pretty quickly if you buy steak meat from the supermarket.
The sauce, made with red wine and onions, isn't a lot of work, and it goes perfectly with the steak, so it's an easy sauce you should definitely give it a try!
We also explained the art of cooking beef steaks with exquisite heat.
Serve with crispy fried potatoes.
Please try making this for a luxurious day at home!
