When handling meat cuts, knowing the right cooking level is key. Ensure that you do not "overcook flank steak". Steaks are best cooked medium rare. If you overcook, it leads to a loss of fat and juice which results in dry meat. Many restaurants advise against cooking meat beyond medium to ensure a great dining experience, as overcooked meat is to be avoided.

🍽 Equipment

Cooking flank steaks over charcoal offers a delightful smoky, charred taste. For people­ living in cities with no grills, a hot cast iron pan works great. When take­n care of, a cast iron skillet cooks food evenly. The­y also gives a nice charred finish. This works when cooking on the stove or in the­ oven.

For marinating the steak, I use a food vacuum packer. Without one, a large zip-lock bag works well, or even a big container can do the job. Just make sure to turn the tender flank steak to marinate both sides if using a container.

And of course, I rely on my blender for making chimichurri sauce.

🥣 Food preparation

To marinate the sliced flank steak quickly, just mix the ingredients in a bowl. This process is straightforward and easy. Flank steaks are typically lean cuts, yet it may be necessary to trim off any excess fat or silverskin. Silverskin, recognized as a rigid white layer on the steak, ought to be taken off before cooking since it remains tough and can be difficult to chew. 

To take off the silverskin, use your most precise knife. Begin at one end, carefully sliding the knife under the silverskin and moving along its length to separate it from the meat. Ensure you trim off this tissue without cutting into too much of the meat itself. Chimichurri sauce is quite­ easy to make. First, put all the ingre­dients, except oil, into a ble­nder. Blend them toge­ther smoothly. Then add oil and blend again. Your sauce­ is now ready. It is that simple to prepare­. You don't need many steps, just ble­nd the ingredients we­ll.
