Wash and dry Sage VERY well. Make sure the leaves are VERY dry so no moisture hits the oil.
Heat the oil up in small saucepan at medium-high heat and allow oil to heat up until thermometer reads 350 degrees Fahrenheit.
Take a few sage leaves at a time..3-5, but don't over-crowd the pot, and add them in. Sage should sizzle.
OK...now this is a QUICK process. Keep your eye on the sage. Keep moving it around and as soon as it stops bubbling, it's done. No more than 30 seconds?.
Have a plate with paper-towel lined on it ready and drop your freshly fried sage leaves atop. Sprinkle with kosher salt.
