Pat the fish with a paper towel, and generously salt both sides
Heat a cast iron skillet over high heat for 2 minutes, then add avocado oil, swirling it around to ensure it covers the bottom of the pan
Lay the fish down, leaving them untouched for 5 minutes- reduce heat to medium high
Ideally, using a metal fish spatula, try to lift the fish. If it does not lift easily, don't force it, give it another 30 seconds to a minute (more if necessary)
After filliping, add the ghee and reduce heat to low, spooning the melted ghee overtop of the fish (you will have to tilt the pan to do this). The fish is finished cooking when it is completely opaque
Remove fish and set aside
