VIDEO: Yours Truly chef Lachlan Culjak shows how much work goes into a single restaurant dish

After watching this video, you may never again feel compelled to complain about dropping too much cash on dinner. Yours Truly chef Lachlan Culjak shows viewers how he prepares a single serving of bone-marrow mousse, a stand-out “snack” on the restaurant’s tasting menu. Each component is treated with the finicky care generally reserved for brain surgery and bomb disposal: over 24 hours, things are brined, pressure-cooked, dehydrated, flash-frozen, deep-fried and pressurized in a carbon-dioxide canister—all to bring diners a few fleeting moments of unadulterated bliss.
