One of my favorite recipes is from the May issue of Bon Appetite magazine, that had a super food-porn pic of steak-frites. I'll have to look for it, but the basic recipe goes like this:
Rib eye steak seasoned with salt and pepper, seared on a ripping cast iron skillet. Take out of the pan, let it rest, deglaze pan with cognac and beef stock, add herbs if you want. Whisk away, scraping all the delicious meat bits stuck to the pan. Add a bit of heavy cream til it reaches your desired consistency, spoon over steak. I have a habit of making too much sauce (never a bad thing), so I spoon that into a little bowl and dip my fries into.
