A fish weight is a simple object, which makes buying one oddly confusing: every listing looks much the same, and the specifications that get advertised are rarely the ones that decide whether the tool works. This guide covers what actually matters, and what is just finish.
First: do you need one?
A fish weight earns its place if you cook skin-on fillets in a pan and you want the skin crisp. That is the whole use case. If you mostly poach, grill, roast or deep-fry, it will sit in a drawer — it works by holding a fillet against a hot surface, and those methods don’t have one.
If you cook fish once a week and the skin keeps coming out pale in the middle and soft at the edges, this is the tool that fixes that specific problem. When to Use a Fish Press — And When Not To is the honest version of that judgement call.
Weight: the only spec that really decides it
Fish curls because the skin contracts faster than the flesh. The weight has to be enough to counter that pull, and no more.
Around 1.5–2 kg is the working range for home-sized fillets. The Fish Weight is 1.6 kg, which came out of cooking a great deal of fish rather than picking a round number.
Heavier is not better. Past a certain point the press stops stabilising the fillet and starts compressing it — squeezing moisture out of the flesh and damaging the skin before it has browned. It also removes your feel for what the fish is doing. How Heavy Should a Fish Press Be? goes through the reasoning.
Footprint: weight is only half the number
What matters is weight spread over area. Two kilograms concentrated into a narrow disc puts far more pressure on the fillet than the same two kilograms spread across a wide one.
The Fish Weight is 16 cm across. That covers most home fillets in one go, still fits comfortably inside a 22 cm pan, and keeps the pressure per square centimetre low enough that the fish is held rather than squashed.
Check the diameter against your pan before you buy anything. A press that doesn’t sit level inside your pan is a press that tilts off the fillet.
The base: flat and smooth, always
Some presses have ridged faces, borrowed from meat tools that are meant to leave grill marks. On fish, ridges crisp the skin in stripes and leave it soft in between.
You want the entire underside making even contact. The Fish Weight has a mirror-polished flat base for exactly this reason — and because a polished surface releases cleanly and wipes clean in seconds.
Material: stainless vs cast iron
Cast iron presses are common and cheap, and they come with cast iron’s obligations: they need seasoning, they can rust, and a rusty or flaking surface sits directly on the part of the fish you are about to eat.
Solid food-grade stainless steel is inert. It doesn’t rust, doesn’t shed anything into the pan, doesn’t need seasoning, and washes up in seconds. For a tool that touches your food every time you use it, that is worth more than it sounds.
One more material note: don’t pre-heat a fish weight. A hot press cooks the flesh from above while you are trying to crisp the skin from below. It goes on at room temperature.
Finish: six colours, one tool
The Fish Weight comes in six finishes, all the same 1.6 kg tool at the same price — the finish is purely how you want it to look hanging in your kitchen:
The coloured finishes are on the exterior. Cooking performance is identical across all six.
Engraving
The weight can be engraved, which is what makes it a good gift for someone who already owns most things — a name, a date, a boat, a restaurant. Have a look at the custom engraving options; engraved orders take longer to dispatch than plain ones, so order earlier than you think you need to.
What to pair it with
The weight works in any flat-based pan with room for it to sit level. If you are buying both at once, the Fish Pan was designed around it: a 22 cm cast iron base with deliberately shallow 2.5 cm sides, so steam escapes instead of pooling and softening the skin you are trying to crisp. The two are sold together in The Crisp Skin Bundle.
A pair of chef’s tweezers is the other thing you’ll reach for, because they let you lift and turn a fillet without gripping it.
Looking after it
Hot water and a cloth. It doesn’t need seasoning and it won’t rust. The polished base means nothing sticks to it for long. There is a small dimple on the underside where the handle is welded on — that is normal and doesn’t affect contact.
Common questions
What size fish weight should I buy?
For home cooking, around 1.6 kg and 16 cm across suits nearly everyone. Match the diameter to your pan rather than buying the biggest one available.
Is a heavier fish press better?
No. Past roughly 2 kg you start compressing the flesh rather than stabilising it, and you lose the feel for what the fish is doing.
Do the different colours cook differently?
No. Same tool, same weight, same base. The finish is aesthetic.
Can I use it on a non-stick pan?
Yes. It rests on the fish, not the pan surface.
Will it work on a barbecue or flat-top?
Yes, anywhere you have a flat hot surface and skin-side-down fish.
Is it dishwasher safe?
It is stainless steel and won’t come to harm, but hot water and a cloth is faster and keeps the mirror polish looking better for longer.
What if I already have a burger press?
It is a different tool built for the opposite job. Here is the full comparison.
