Turns out, Brown is not the only person to experiment with mayo as an oil for cooking steak. There are a number of videos online for mayonnaise steak and people seem to love it.
As crazy as it might seem, mayo is made up largely of oil and the other ingredients, egg, lemon and a little vinegar would also add some seasoning.
A quick read through the comments on Brown’s Instagram page and it’s obvious that many people use mayo as a substitute for oil. One user wrote, “Grandmas secret, surprised you’re surprised?! Sous vide in mayo for 1-2 hours and then sear on an iron skillet.”
