Flathead w/ Sweet & Sour Tomatoes

One of the things we love most about our job here at One Hour Out is discovering places like Captain Moonlite. It’s a sea-change for chef Matt Germanchis (Pei Modern, MoVida, Pandora’s Box) and partner Gemma Gange (Pei Modern, Jacques Reymond, Stokehouse). Now a firm OHO fave, Matt and Gemma have been generous enough to share this crowd-pleaser of a dish with us.
