What Is Glatt Kosher? The Smash House Standard Explained
Glatt Kosher is a standard that applies specifically to kosher meat. Glatt means “smooth” in Yiddish and refers to the condition of an animal’s lungs after shechita, or kosher slaughter. Meat classified as glatt has passed a stricter lung inspection standard involving adhesions that could affect its kosher status.
For a restaurant, though, there is more to kosher certification than the beef. Smash House operates locations under different kosher arrangements, including locations with Glatt Kosher certification, so diners should check the current certification for the restaurant they plan to visit.
What Does Glatt Kosher Mean?
The Glatt Kosher meaning starts with one very specific part of kosher meat inspection: the lungs.
It does not technically mean that a restaurant, french fry or piece of chicken has “smooth lungs.” The phrase has simply taken on a broader meaning in everyday kosher food language.
The Literal Translation
Glatt is Yiddish for smooth.
In traditional kashrut terminology, it refers to an animal whose lungs do not contain adhesions that raise a kosher concern.
Today, people also use Glatt Kosher more generally to describe meat or establishments operating under a more stringent kosher standard. That broader use is common, but it helps to know where the term actually came from.
The Lung Inspection Standard
After kosher slaughter, the lungs of the animal are inspected.
This matters because certain defects can render an otherwise permitted animal non-kosher. Lung problems receive particular attention because punctures and adhesions can indicate an issue under Jewish dietary law.
The inspection is carried out by someone trained to assess whether the lungs meet the required standard.
What Adhesions Are & Why They Matter
Lung adhesions, known as sirchot, are areas of tissue that may indicate a defect or potential perforation.
This is where different kosher standards can come into play.
Under some accepted Ashkenazi practice, certain minor adhesions can be examined and tested before the meat is declared kosher. Glatt Kosher meat follows a stricter approach to questionable adhesions.
There is also Glatt or Chalak Beit Yosef, a standard followed particularly within Sephardic practice that applies stricter rules to adhesions.
Glatt Kosher vs. Basic Kosher: What's the Difference?
All glatt meat is kosher, but not all kosher meat is necessarily glatt.
That’s the useful distinction.
The Difference Is in the Meat Standard
A properly slaughtered animal can still be considered kosher under some accepted standards even when certain minor lung adhesions require further examination.
Glatt Kosher beef meets the stricter glatt standard used by the relevant certifying authority.
So “regular kosher” does not mean “not properly kosher.” It means the meat may follow a different accepted standard.
Why Glatt Is Considered a Stricter Standard
The difference comes down to what types of lung adhesions are accepted and how they are evaluated.
It is therefore more accurate to say that glatt follows a stricter meat standard than to call it “more kosher.”
Kosher status is not a points system.
Who Looks for Glatt Kosher Meat?
Many Orthodox Jewish consumers specifically look for certified Glatt Kosher meat.
Requirements can differ between communities and families. Sephardic consumers may specifically look for Chalak Beit Yosef, while other observant diners follow the standards accepted by their own rabbinic authority.
That is why the name of the kosher certifier matters, not simply the word “kosher” on a restaurant website.
How Glatt Kosher Certification Works
A restaurant’s Glatt Kosher certification covers much more than inspecting the beef that arrives at the door.
The certifying organization also considers ingredients, suppliers, food preparation and how the kitchen operates.
The Role of the Mashgiach
A mashgiach is a kosher supervisor.
Depending on the certifying agency and type of establishment, the mashgiach may oversee incoming ingredients, cooking procedures, equipment and other areas that could affect kosher status.
For example, OU-certified restaurants use on-site kosher supervision to make sure the required standards continue to be followed during normal restaurant operations.
Who Issues Glatt Kosher Certification?
There isn’t one national agency responsible for every Glatt Kosher restaurant.
Organizations such as OU Kosher, Star-K and regional rabbinic authorities provide kosher certification. Restaurants may therefore operate under different recognized supervising agencies depending on their location.
The standard a diner follows may affect which certifications they personally accept.
What the Certification Process Looks At
The exact process depends on the certifier.
For a meat restaurant, supervision can include checking approved suppliers and ingredients, confirming the kosher status of the meat, reviewing equipment and monitoring kitchen procedures.
Certification is ongoing. A restaurant doesn’t simply receive approval once and then operate without oversight.
What Glatt Kosher Means at Smash House Burgers
Smash House was created around serving kosher smash burgers, but its current locations do not all carry identical kosher status.
The company’s own guidance says some Smash House locations operate under Glatt Kosher supervision, while others are described as kosher-friendly.
How Smash House Handles Kosher Status
Smash House’s broader menu is built around kosher dining, including meat burgers made without dairy ingredients.
However, if strict certification matters to you, check the individual location rather than assuming the same kosher standard applies across the entire group.
That distinction matters more than a broad chain-level label.
A Current Glatt-Certified Example
Smash House’s Lakewood/Toms River location currently states that its entire menu is 100% Glatt Kosher certified under Tartikov Kashrus, led by Rabbi Yechiel Babad.
The Smash House Burgers Brooklyn page separately describes its kitchen as 100% kosher and certified kosher.
The sensible approach is to check the certification shown for your specific restaurant before ordering if you follow a particular standard.
What It Means for the Menu
At a location operating under Glatt Kosher certification, the standard isn’t limited to the burger patty.
The restaurant’s meat sourcing, approved ingredients and kitchen handling must all fit the requirements set by its supervising certifier.
That is why kosher restaurant certification is broader than simply buying kosher beef.

Why Glatt Kosher Matters to Customers
For someone who keeps glatt kosher, certification isn’t an interesting extra. It determines whether they can eat at the restaurant.
For the Observant Jewish Community
Clear certification removes guesswork.
Customers can see which authority supervises a restaurant and decide whether that certification meets the standard they follow.
That is particularly important as Smash House expands into communities with different kosher expectations.
For Diners Who Want Clear Information
Even if you don’t personally keep kosher, certification gives you more information about how ingredients and kitchen procedures are controlled.
But transparency also means being precise about the terminology.
Calling every Smash House location Glatt Kosher when the company’s own site says otherwise would make the information less useful, not more.
Check Before You Order
Kosher status can vary by location, so use the current restaurant page or contact that store when a specific kosher certification matters to you.
You can find a Smash House Burgers near you and check the location details before visiting.
Frequently Asked Questions
What Is the Difference Between Kosher & Glatt Kosher?
Kosher is the broader set of Jewish dietary requirements. Glatt Kosher technically refers to a stricter standard applied to meat based on the condition and inspection of the animal’s lungs.
Is Glatt Kosher Stricter Than Regular Kosher?
Yes, when discussing the meat standard. Glatt places stricter limits around questionable lung adhesions. That does not mean meat accepted under another recognized kosher standard is automatically non-kosher.
Is Smash House Burgers Glatt Kosher Certified?
Some locations are. Smash House’s current site states that some restaurants operate under Glatt Kosher supervision, while others are kosher-friendly. Check the certification for the individual location before visiting.
What Does Glatt Mean in Hebrew?
Glatt is actually a Yiddish word meaning “smooth.” The Hebrew equivalent is chalak. In kosher meat terminology, the term refers to the condition of the animal’s lungs.
Do All Kosher Restaurants Serve Glatt Kosher Meat?
No. A restaurant can operate under an accepted kosher certification without necessarily serving meat classified as glatt. Kosher standards and certifying authorities vary, so diners who specifically require glatt should check the restaurant’s supervision.
