Commercial Karahi & Deep Wok Buying Guide: Sizes, Materials & What Restaurants Actually Use (2026)
Who This Guide Is For
If you run an Indian, Pakistani, Nepali, Middle Eastern, or South Asian fusion restaurant — or any kitchen that needs a deep, round-bottomed heavy-duty wok for curries, biryanis, deep frying, or large-batch cooking — this guide is for you.
Most commercial kitchen supply stores (including the large US chains) stock standard flat-bottomed Chinese-style woks. Those work for stir-fry. They don't work for the deep, sustained curry cooking, high-BTU tadka, or large-volume dal preparation that South Asian and Middle Eastern kitchens demand. A karahi (also called kadai or kadhai) is a different tool — deeper, heavier-gauge, and designed for a completely different cooking style.
This is the guide those stores don't write.
If your Indian restaurant kitchen still uses a home karahi on a commercial burner, you're leaving money — and safety — on the table. The right commercial karahi doesn't just hold more food. It distributes heat correctly, survives daily abuse, and handles the BTU output of a real commercial range without warping.
This guide covers everything a restaurant owner or kitchen manager needs to know before buying: materials, sizes, handle types, wok vs. karahi, and what real restaurant kitchens use.
What Is a Commercial Karahi (and Why It's Different From a Home One)?
A karahi is a deep, round-bottomed Indian wok used for everything from curry to deep frying. In a home kitchen, a 2–3 litre karahi is standard. In a commercial kitchen, you're looking at 12 to 30+ litres, made from heavy-gauge aluminum or stainless steel, with reinforced handles that won't melt under sustained heat.
The key differences: - Gauge thickness: Commercial = 4–6mm walls. Home = 1–2mm. Thin walls warp on high BTU burners. - Handle design: Commercial handles are riveted or welded, not pressed. They don't come loose mid-service. - Flat vs. round bottom: Commercial kitchens with flat-top ranges need flat-bottom karahis. Traditional chulha or open flame setups use round-bottom. - Surface: Aluminum heats faster. Stainless steel lasts longer and is NSF-compliant for most US health codes.
Commercial Karahi Sizes: What to Buy for Your Kitchen Volume
| Kitchen Volume | Recommended Size | Capacity |
|---|---|---|
| Small (under 50 covers) | 12–16 litre | 8–12 portions per batch |
| Medium (50–150 covers) | 18–24 litre | 15–20 portions per batch |
| Large / Catering | 28–36 litre | 25–35 portions per batch |
| Buffet / Banquet | Multiple 12L + chafing | Maintain temp + replenish |
Pro tip from restaurant kitchens: Most Indian restaurants buy one size smaller than they think they need for sauté/tadka work (high heat, small quantity) and one size larger for biryani-base curries and dal makhani. Two different karahis for two different jobs.
Stainless Steel vs. Aluminum: Which Is Right for Your Restaurant?
Stainless Steel Karahi
- NSF/food-grade compliant — meets US commercial kitchen requirements
- Doesn't react with acidic ingredients (tamarind, tomato, amchur)
- Heavier — harder on wrist during long shifts
- Higher upfront cost, longer lifespan (5–10+ years commercial use)
- Best for: High-volume Indian restaurants, caterers, health inspection environments
Aluminum Karahi
- Lighter — easier to maneuver during busy service
- Heats faster and more evenly on gas burners
- Reacts slightly with acidic ingredients over time
- Lower cost — practical for backup or secondary cooking
- Best for: Deep frying (samosas, pakoras), dal, non-acidic preparations
Our recommendation: Use stainless steel as your primary karahi for curries and sauces. Keep aluminum for deep fry work where heat speed matters more than reactivity.
Karahi vs. Kadai — Are They the Same Thing?
In commercial kitchen supply catalogs you'll see both terms used. They refer to the same vessel. "Karahi" is the Punjabi/Urdu term; "Kadai" or "Kadhai" is the Hindi/South Asian term. Same round-bottomed, two-handled wok. When shopping, search both terms to find the full range.
What to Check Before You Buy: 5-Point Inspection
- Gauge marking: Ask for the gauge number. 14-gauge stainless is good. 18-gauge is too thin for commercial use.
- Handle weld/rivet quality: Tug the handle. It should not flex at all.
- Base flatness: On flat-top ranges, a curved base means hot spots and instability.
- Weight: A 16-litre commercial karahi should weigh at least 2.5 kg empty. Lighter = thinner metal.
- NSF marking: If your local health department requires NSF-certified equipment, confirm the product carries it.
Where to Buy Commercial Karahi in the USA
Most restaurant supply stores in the US stock generic woks but not Indian-specific karahis in commercial sizes. Specialty Indian restaurant supply stores are your best source for: - The right depth-to-width ratio (Indian karahi is deeper than a Chinese wok) - Sizes above 16 litres - Handles designed for the Indian grip style
At Celebrate Festival Inc, we carry heavy-duty aluminum and stainless steel karahis in sizes from 12 to 30 litres, shipped from our Fremont, CA warehouse to restaurants across the US.

Frequently Asked Questions
Q: What size karahi does a typical Indian restaurant need? A: For a restaurant serving 50–100 covers, an 18–24 litre karahi covers most curry and dal work. Keep a smaller 12-litre for tadka and finishing.
Q: Can I use a karahi for deep frying in a commercial kitchen? A: Yes — aluminum karahis are commonly used for deep frying samosas, pakoras, and jalebi in Indian restaurant kitchens. Use one dedicated to frying to avoid flavor transfer.
Q: What's the difference between a karahi and a wok? A: A karahi is deeper with a narrower diameter relative to its depth, designed for slow-cooked Indian curries. A Chinese wok is shallower and wider, built for rapid stir-fry. They're not interchangeable for Indian cooking.
Q: How long does a commercial karahi last? A: A heavy-gauge stainless steel commercial karahi used daily in a restaurant kitchen should last 5–10 years. Aluminum lasts 2–5 years depending on how acidic the food you cook in it is.
Q: Is a karahi NSF certified? A: NSF certification depends on the specific product. If your local health code requires NSF-certified equipment, look for products that explicitly carry the NSF mark. We stock NSF-compliant options — contact us to confirm for your specific requirement.
