Sous-Vide Skirt Steak Fajitas

Besides short ribs, skirt steak is also one of my newer discoveries, having taken greater interest in all cuts of beef.

I learned from my local butcher that skirt steak is popular with Mexican and Chinese restaurants, commonly used for fajitas and stir fries as it's less expensive. Tough and lean, it requires marinade to further tenderise and impart flavour.

Sous-vide really brings out the best in this steak fajita recipe. I really love Tex-Mex spice combinations and here it blends with the ultra tender rare beef to create a truly sumptuous treat!

Once the steak is ready, remove it from the bag, pat dry and season both sides with salt. Heat 1 tbsp of oil on a heavy based skillet until hot. Sear the steak on high heat for 25 seconds per side. Slice the meat thinly against the grain.

Notes & Tips

Pre-searing not only helps kill off the surface bacteria on the meat, but also jump-starts the amazing flavor creation that develops over the long cooking time.
