Expert Review and Insights
It’s refreshing to see an accessory that so perfectly complements its parent appliance. This isn’t a generic, flimsy pan; it’s a solid piece of kit engineered to take the brutal heat of a Josper day in, day out. The cast aluminium build makes a tangible difference to heat retention and searing, something standard stainless steel just can't replicate at these temperatures.
Sophie Brooks – Chef Tools View Profile →
- Built to Last: The robust cast aluminium construction is superb and simply will not buckle under pressure.
- Specialised Use: It’s a specialist tool, less versatile than standard GN pans for general kitchen tasks.
Case Study: Real Business, Real Results
The team at 'The Coal Shed', a popular grill house in Cardiff, recently upgraded to a Josper oven but found their existing stainless steel pans were warping from the intense heat, causing inconsistent cooking and slowing down service.
"We were fighting with our old pans every night; they just couldn't handle the heat. Switching to these official Josper trays was a revelation. They are solid, reliable, and the heat distribution is spot on. It's a small change that has made a huge difference to our consistency and workflow."
Michael Davies – Head Chef
The kitchen now reports a smoother service, with zero delays caused by failing equipment and a noticeable improvement in the char and cook on their vegetable side dishes.
Installation and Maintenance Guide
Setting It Up
- Before first use, wash the tray with hot, soapy water and dry thoroughly.
- For best results, 'season' the tray like you would cast iron: lightly oil, heat it in the oven, let it cool, and wipe clean.
- Always pre-heat the tray in the Josper oven for a few minutes before adding food for an instant sizzle and sear.
Keeping It Going
- Always allow the tray to cool down before washing to prevent thermal shock, which can damage it over time.
- Hand wash only. The harsh detergents and high heat of a commercial dishwasher can degrade the material.
- Use scrapers and cleaning tools suitable for cast metal; avoid overly abrasive scouring pads.
- Ensure the tray is completely dry before stacking to prevent any moisture from being trapped.
Frequently Asked Questions
Q: Can I use this tray on a standard gas hob or induction top?
A: No, this Josper gastronorm pan 1/3 size is specifically designed for use inside high-temperature ovens like the Josper charcoal oven or Basque grills. It is not suitable for direct hob use.
Q: Is the tray non-stick?
A: It doesn't have a synthetic non-stick coating. However, like cast iron, it can be seasoned with oil over time to develop a naturally low-stick surface.
Q: Is this Josper oven 20mm deep tray dishwasher safe?
A: We strongly recommend hand washing only. The harsh chemicals and high temperatures in commercial dishwashers can damage the cast aluminium and affect its performance.
Q: Will this tray warp like my stainless steel ones?
A: It has been engineered from cast aluminium specifically to resist warping and buckling under the extreme temperatures found in charcoal ovens.
Q: What does '1/3 Gastronorm' actually mean?
A: Gastronorm (GN) is a European standard for kitchen container sizes. A 1/3 size means three of these trays will fit perfectly into a standard 1/1 GN rack or counter opening.
Q: Can I use it in my regular convection oven?
A: Yes, absolutely. While it's optimised for Josper ovens, it will perform brilliantly in any commercial oven where a robust, shallow tray is needed.
Q: Is it heavy to handle?
A: At 750g, it's reassuringly solid but not overly heavy. It's much lighter than a cast iron equivalent of the same size, making it easier to manage during a busy service.
Q: Why is it black?
A: The black colour is characteristic of the cast aluminium and its finish, which is designed to optimise heat absorption and radiation within the oven.
The Josper Difference: An Investment in Consistency
Buying official Josper oven accessories isn't just about getting a tray that fits; it's about upholding the integrity of your entire cooking system. The collaboration with grilling authority Bittor Arginzoniz is a testament to this philosophy. This isn't a mass-produced, one-size-fits-all product. It's a calculated piece of engineering designed to work in perfect harmony with the unique cooking environment of a Josper oven. Using the correct, purpose-built tools minimises equipment failure, eliminates the costly issue of warped pans, and, most importantly, delivers the consistent, repeatable results your customers expect. Think of it as an investment in performance – a way to ensure that every dish that leaves your kitchen has that unmistakable Josper character, from the first service to the last.
Why Cast Aluminium Makes All the Difference
Ever wonder why a proper cast iron skillet gives a better crust on a steak than a thin frying pan? It's all about holding and transferring heat. This Josper charcoal oven gastronorm tray works on the same principle. Standard stainless steel pans are great all-rounders, but under the extreme, direct heat of a charcoal oven, they can develop hot spots or even buckle – like a cheap baking sheet twisting in your home oven.
Cast aluminium, however, absorbs that intense energy and distributes it evenly across the entire surface. This means no surprise cold spots and a consistent, reliable sear every time you use it. It’s the difference between simply cooking your food and truly finishing it with that signature, smoky, perfectly-caramelised Josper character.
Who Should Buy This?
- Premium Steakhouses: Essential for perfectly searing sides like asparagus or mushrooms to accompany prime cuts of beef.
- Authentic Tapas Bars: The ideal size for cooking and serving sizzling portions of gambas al ajillo or padrón peppers.
- Fine Dining Restaurants: Offers precise heat control for delicate items like fish fillets or scallops in the charcoal oven.
- Gourmet Pubs: A brilliant tool for elevating pub classics, like roasting off individual portions of root vegetables.
