Reverse sear changed my life more than any meditation app ever could. Low oven (120°C) for 45 minutes, then screaming hot cast iron for 90 seconds per side. Edge-to-edge medium rare with a crust that sounds like breaking glass. Zero gradient, zero grey band, just 3cm of perfect pink topped with salt crystals the size of your regrets. Every steak I ruined before learning this technique was a lesson in impatience. High heat from the start = charred outside, raw inside, lies about 'letting it rest'. Low and slow builds the foundation. Nuclear sear delivers the drama. Physics beats intuition. Thermodynamics beats tradition. A 2 thermometer beats your uncle's 'touch test' that's been wrong since 1987.
