Dry-aging isn't a marketing term here. It's a room, it's a schedule, and it's the reason the beef tastes the way it does.
The point where the beef reaches its aroma, flavor and tenderness — without going past the point of diminishing returns.
Every cut ages inside a well-circulated, humidity- and temperature-controlled room built for the purpose.
The balance of marbling to meat. Dry-aging increases that ratio, which is what separates these cuts from everything else in the case.
Step inside and pick out your own cut, the same way Frank Sr. does. Ask — we'll take you in.
One family, one trade, four generations of New Jersey butchers.
An eighteen-year-old Frank M. DeRosa, just back from basic training, stands with his sister Lillian and their parents outside the family home and store on 4th Street. He would ship out to serve in World War II, come home, and spend the rest of his life in the trade his father started.
An Italian immigrant with a dream of running his own family business, F.A. DeRosa purchases Liberty Food Market in Newark, New Jersey. He gives the trade — and the name — to his son.
Serves his country in the Army Air Force during World War II, then settles in Union County. He works at the Westfield Market, then Rose's Market in Garwood, before joining a meat purveyor at the Plainfield Cold Storage Building and helping establish Meat City, a retail and wholesale supplier in Linden with a second location in North Brunswick.
His name becomes sought-after in the industry. He runs the meat department at ShopRite in Dunellen, then is promoted to the larger department at the new ShopRite in Middlesex. In retirement he partners with his wife Clementina to buy J&M Market in Mountainside, where he teaches his two sons the trade — selling them the business in 1986.
Spends nearly 25 years in the family business at J&M Market. He goes on to work as meat manager at Kings Supermarket in Berkeley Heights, then as a supervisor at Village Supermarkets, overseeing eight ShopRite meat and seafood departments until his retirement in 2017.
Worked as a clerk at his family's J&M Market as a child, then left for a career in international business development and marketing. When his grandfather passed away, he realized his true calling was the trade he'd grown up in.
He convinced his father out of retirement. Together they opened their own family-operated butcher shop — first in downtown Westfield, and now in Mountainside, returning the family to the town J&M Market served for decades.
"I head into Manhattan once a week and personally choose every single piece of meat that's hanging in this cooler. It's me and the guy from Peter Luger's standing there going over every inch."
Every primal Frank Sr. selects is marked with the shop's own brand, so nothing can be mixed up in transport. Nothing here is boxed meat — it comes fresh, direct from the Midwest, and it's cut where you can watch it happen.
"We have no secrets here. We're proud of what we're doing, so why not let everybody watch us do it?"
A wall mural by artist Brian Holderman adorns the Mountainside shop — a welcome to the historic town this family has called home for generations, and a marker of their place in the community. Come see it in person.
Private First Class Frank M. DeRosa served in the Army Air Force during World War II, alongside his older brother Johnny. Mountainside honors him on a banner on the post directly outside our shop.
Seeing it there every day is a reminder of the courage and dedication that continue to shape this business — and our gratitude to everyone who served.
"I've been to some of the best butchers in the tri-state area. This is the best."
"I grew up in a family of Butchers and this shop simply has the best beef anywhere."
"What a wonderful, old school butcher shop. Been to many fancy steakhouses in NY. Luger, Bowery Meat Co, Homestead and more... always good but just okay. We got the Porterhouse at 1¾" cut. It was amazing."
"Frank special ordered this leg of lamb for my family, and when it didn't arrive quite on time he offered to deliver it to us 30-40 minutes away. Exceptional customer service and the highest quality product. This is where to shop."
"Excellent customer service! I was able to place an order for an item that wasn't in stock, and they promptly called to notify me when it arrived. Frank, Ray, and Liam run a wonderful family business — definitely my go-to spot for fresh, high-quality, aged meats."
"This place absolutely exceeded my expectations. It was my first time in a butcher and the gentleman behind the counter was kind, thorough, and provided recommendations based on our preferences. They were also so close to closing but he still brought me into the walk in to show me around and explain how they dry age their meat."
"Absolutely wonderful experience and product, from the upfront and transparent discussion around pricing, to the expert selection and custom cut to order, to the ultimate end product cooked to perfection and enjoyment by all."
"Great friendly people and the best Sausage and Burger I've ever had. An absolute gem."
"Best butcher in the state and probably even further."
