Netherton Foundry Croustade Iron

Shropshire made, Croustade iron 

A croustade iron is the perfect way to make deep fried canapé shells.

It's not a new idea, basic croustade irons have been used for years in Scandinavia making traditional sweet and savoury batter shells. This has been rediscovered by a new generation of modern British chefs who are using this classic technique to produce a very exciting way of presenting flavours and textures, we've seen them used to make canapés, starters, amuse bouches, desserts and confectionery.

It's made from......

The batter form is made on a lathe from a solid bar of aluminium. This is hand polished to ensure each shell releases easily.

Using a stainless steel bolt we attach the form to a Netherton Foundry 3mm thick black iron handle.

The durable 99.1% pure iron handle is pre-seasoned with flax oil for a natural non-stick finish & easy to clean.

We then add our signature hand made, British oak handle covers with brass fixings.

 

How do you use it........

To make the shells, first you will need to make a batter, see below for some recipe advice.

Add your chosen oil to a depth of 1½inch ( 4cm)  in a saucepan, a 
Netherton Foundry 6 inch saucepan
is perfect for this, alternatively use an electric deep fat fryer. 

Heat the oil up to frying temperature, this will vary depending on the oil you choose but we suggest not less than 160ºC and a maximum of 200º centigrade (320º to 390º Fahrenheit).

We recommend using a high temperature frying oil such as sunflower, corn, soybean, rapeseed (canola) or peanut oil. We do not recommend flax seed, nut or olive oils for deep frying. 

 

 

Once the oil is up to temperature, pre-heat the croustade iron in the hot oil for about 15 seconds.

Then dip the croustade form into the batter up to the level of the shoulder.

 

 

Now place the croustade iron into the oil up to the top of the form.

 

 

Hold it here until the shell batter is golden brown, this will take around a minute. 

 

 

Remove from oil and immediately remove the fried shell from the form using a clean cloth, remember the form will be very hot and will burn you if touched.

Dimensions:

Weight 0.34kg (12 oz).

The total length of the form and handle is 40cm (16 inches).

This makes a croustade shell 3cm (1
⅛
 inch) in diameter and 2cm (
¾
 inch) deep. 

 

We also have these croustade irons if you plan to make lots of shells.

Why does Netherton Foundry make croustade irons?

Simple, we were asked to by a couple of very talented chefs!

We love working with creatives with great ideas. In 2020 we made our first Croustade Iron for Simon Martin at 
Mana, Manchester,
this was very much a one off and was essentially a copy of a traditional iron.

In 2021, Luke from 
JÖRO, Sheffield
 asked us to produce first a single, a double and finally a quadruple croustade iron.  Clearly we needed to think big, so we developed a truly Netherton Foundry solution.

Lizzie Frainier wrote about JÖRO in the Daily Telegraph: 

10 / 10  Food and Drink: Naturally, this is where JÖRO really shines, with a choice of five-, eight- or 10-course tasting menus that combine Nordic and Asian flavour profiles with aplomb. An amuse-bouche of Montgomery cheddar and onion croustade delivers a rich and savoury explosion of cheese that sets the tone for the punchy dishes that follow. Highlights on my visit included a sweet, fat Orkney island scallop, caramelised on the plancha (grill), and topped with scallop roe, puffed jasmine rice, and a riotous red curry sauce; as well as the tender West Country venison adorned with celeriac spheres and fiery mustard, matched to an Austrian Judith Beck Ink wine with notes of cherry and a satisfyingly smoky finish. 

Sometimes breakfast the next day after a particularly excellent meal can be a disappointment – not here. A breakfast hamper is done up to the nines with only the best ingredients on offer. Freshly baked white and wholemeal croissants come from the restaurant, but there’s also slices of London Cure Smoked Salmon, Lishman’s delicate cured meats, ooey-gooey Loire Valley Comte and more.
