Tamari Cured Egg Yolks


This is a new technique I developed for curing egg yolks in tamari. The results are truelly delicious, the tamari cured yolks have a parmesan like flavour but also still something unique and not quite the same as an aged cheese. When I taught this technique in Athens a number of the chefs said it tasted like bottarga. But whatever you liken it to it is a stand out delicious product that can bring a big kick of umami to a variety of dishes. You can see the technique in the video bellow and the full recipe is given at the end of this post.


There are simpler, traditional methods for curing yolks in salt but I found that the results can be overly salty. I wanted something less salty but with lots of umami and a more complex, aged flavour. After trying a few different approaches, some trial and error and then time spent refining the method I arrived at this technique which I now use all the time. The yolks are cooked in a tamari cure (extra salt and sugar is added to the tamari) in a waterbath at 62°C for 6 hours. In this time the yolks are cured and set, then the cured yolks are dehydrated until completely dry. The finished tamari cured yolks can be grated finely with a microplane.

The dish pictured is from my upcoming book which should be released in May. It is a take on a salad with confit potato and fresh peas dressed in smoked yoghurt and hidden under a generous grating of the tamari cured egg yolks.

I’ll also be serving dishes featuring the tamari cured yolks at my upcoming
supper clubs, so if you are in the Manchester area you can come and try them in person.


Tamari Cured Egg Yolks

Tamari cure liquid
200g Tamari
20g Sugar
20g Salt

Blend the ingredients for the tamari cure liquid together and place in a squeeze bottle.

For each egg yolk

Cut a piece of cling film and place over a cup.
Separate an egg yolk from the white.
Place the yolk in center of the clingfilm.
Pour the tamari cure over the yolk.
Pinch clingfilm together to form a package - excluding as much air as possible but careful not to break the yolk.
Twist the cling film to secure the package.
Clip the clingfilm packages in place.
Trim the excess clingfilm off.


Carefully place the packed egg yolks into the waterbath on a low circulatory flow.
Cook the yolks for 6 hours at 62
Once cooked carefully remove yolks from their clingfilm packaging and pour away the tamari cure.
Finally dehydrate the cured yolks at 68
°C for 6-8 hours until completely dried.
Store in an airtight container in the fridge until needed.


Ahtens - Modern Vegetarian Cuisine Course

This is just a short blog to share a few photos from the course I recently taught in Athens. You can see a full gallery of around 60 images from the course by clicking here.

The course was titled 'Modern Vegetarian Cuisine' and was targeted at chefs working in high end restaurants and hotels, organised by
Gastronomy Essentials.

I showed 22 dishes over two full days of teaching and we served tasters with every dish, so it was a very ambitious programme and a lot of hard work, but with the help of the fantastic team I had it went brilliantly and we got an overwhelmingly enthusiastic response from the 50 chefs attending the course.

I'd like like to especially thank Harry from
Gastromony Essentials for organising the course, Fay for heading up the kitchen team, and the rest of the chefs I worked with for all their hard work, as well as the chefs attending the course for their enthusiasm.

If you are interested please take a look at the
full gallery and look out for information on things like this that I’m up to by following me on the Blog, Twitter and Facebook

Modern Vegetarian Cuisine Course - Athens


I will be teaching this course in Athens in february 2015.

The focus of the course is modern vegetarian cuisine and I’ll cover a lot of topics over the two days, introducing and explaining techniques through a series of my own modern dishes which I will present, along with tasters.

I’m still finalising the dishes for the course but some things that will definitely be covered include -

Vegetarian applications of sous vide
Vegetarian uses of transglutaminace
Sous vide ‘caramelisation’ in various products
Using seaweeds
Umami in vegetarian cooking
Vegetarian gelling agents and techniques
Various vegan desserts
Modern presentation and ideas
and much more...

I hope you can join me in Athens in 2015

All the best


Easy Sous Vide Chocolate Ice-Cream


Rich Chocolate Ice-Cream - Sous Vide

This incredibly rich, luxurious chocolate ice-cream is simple to make with the precision of sous vide cooking and will seriously impress every time!

It’s got an immense intensity of flavour from the dark chocolate and a perfect rich, smooth texture which is always spot on and consistently repeatable with the accuracy of sous vide cooking.


For the ice-cream base the sous vide method aids consistency, accuracy and makes the ice-cream making process easier and neater. This means you get fantastic results every time and have more free time, so its an ice-cream technique that suits home cooking when you are busy or can allow you to focus on more technical culinary exploits knowing your ice-cream is taken care off.

The cooked ice-cream base will keep in its vacuum bag in the fridge for up to a week before being frozen. So it can actually be made well ahead of time but frozen as close to serving as possible to prevent the formation of large ice crystals and so keep a beautiful smooth texture.



500g Double cream
250g Dark chocolate (70% cocoa solids)
150g Caster sugar
150g Whole milk
50g Butter
110g Egg yolks (approx 6 free-range medium egg yolks)
Pinch salt

First melt the chocolate and butter either in the microwave or in a bowl placed over a pan of simmering water.

Now bit by bit stir the cream into the melted chocolate.

Combine this chocolate and cream mixture along with all the other ingredients in a blender and puree until the mixture is completely smooth.

Now split this ice-cream base between two vacuum bags and seal in a chamber vacuum at approximately 40% vacuum (the vacuum strength is relatively low to prevent the ice-cream mix bubbling up out of the bag) or seal the mix in ziplock bags excluding as much air from the bags as possible.

Place these bags of ice-cream base into a waterbath at 82°C, the water temperature will briefly drop, as soon as the temperature climbs back to 82°C start a timer for 20 minutes.

Cook the ice-cream base for 20 minutes at 82°C then remove the bags from the water bath and immediately chill in cold water while squeezing the bag to ensure the contents are moved around well.

You can store this ice-cream base in its in the fridge for up to a week before freezing, or freeze immediately by your preferred method, I use a simple ice-cream machine at home.

Let the ice-cream soften at room temperature before serving.

Modernist Marshmallows (Vegan)


Picture - My new marshmallow technique applied for Gin & Tonic Marshmallows (a dish which will be in my next book)

Probably once a month I get an email asking me for a good vegetarian marshmallow recipe and I have now finally gotten around to creating one. In fact in the end it turned out the way to make the best marshmallow possible was actually to make a vegan recipe - there are two big advantages to this -

1) Everyone can eat these (they are Vegetarian & Vegan, Gluten Free etc)

2) This technique for making marshmallows allows you to add flavours, alcohol etc into the marshmallow mixture itself (in fact I just finished a recipe for Gin and Tonic Marshmallows based on this technique).

So not only are these marshmallows vegan but they can be flavoured in ways that traditional marshmallows can not (including adding alcohol into the mixture).

The texture and taste of these marshmallows is genuinely identical to traditionally made marshmallows, in fact they can even be toasted like traditional marshmallows!


These marshmallows can be toasted just like traditional marshmallows!

While the technique may appear to be a little complex if you are not familiar with some of the ingredients, it is worth the effort as it gives you incredible results. If you read the recipe well beforehand, measure out all your ingredients, and work in an organised way this recipes should be achievable for everyone.

The modern ingredients used in this recipe are available from -

Other vegetarian marshmallow recipes often over simplify and call for agar, a gelling agent which is great for some things but does not set with the correct texture for making soft marshmallows. So here I use a combination of Kappa Carageenan and Locus Bean Gum, which when used in synergy create a gel with the same texture as a gelatine gel. This is perfect for texture we want in marshmallows.

Then in the place of egg whites this recipe uses Methylcellulose, which is a modern ingredient derived from plant cells that acts as a whipping agent - allowing us to whip the marshmallow base into a very stable foam (even more stable than egg whites would be). And using methylcellulose also means flavourful liquids can be whipped into the marshmallow base, opening up a huge range of potential creative flavour possibilities.

Its also possible to add freeze dried fruit, nuts, spices etc to the marshmallow base once it has been whipped, so it’s really easy to make some interesting, exciting, flavoured marshmallows.

My Basic Modernist Marshmallow Recipe
This can be adapted for a range of flavours

Before you try making this recipe read it though well and measure out all your ingredients. The hydrated methycellulose slurry can be made well in advance and stored in the fridge or even frozen indefinitely (see the end of this post for detail on how to prepare the hydrated methylcellulose).

I Hope you enjoy the recipe

Before you begin lightly grease a small baking dish then dust it with 50/50 mixture of icing sugar and cornflour. Then set this dish to one side

Marshmellow Base

50g Hydrated Methylcellulose Slurry (See the bottom of this post)
100g Caster Sugar
60g Water (or flavourful liquid)
1g Xanthan Gum
2g Vanilla Essence (approximately a teaspoon)
0.2g Rose Water (a drop)

Combine all the above ingredients except the sugar in a bowl and begin whipping them (ideally in a a stand mixer).

Slowly add the sugar into this this mixture whilst whipping.

Continue to whip until the mixture forms stiff peaks (like an egg white meringue)


200g Sugar
60ml Water

Combine the sugar and water in a pan and slowly heat until the mixture reaches 125°C.


150g Water
3.5g Kappa Carageenan
2.2g Locus Bean Gum (or 4.5g Biozoon Brand Locuzoon)

Once the temperature reached syrup has hit 125°C slowly whisk in the the 150g Water (being careful as the mixture may spit and bubble).

Then adding a bit at a time whisk the Kappa Carageenan and Locus Bean Gum into the hot syrup.

Stir this mixture well for approximately two minutes (the mixture will be consistency of a thick syrup).

Now for the next stage you need to work quickly.

Gently but swiftly pour the hot syrup mixture into the whipped marshmallow base whilst whisking the marshmallow base.

Then as soon as the syrup mixture is mixed into the marshmallow base pour the whole mixture out into the prepared, dusted baking dish, smoothing out the top of the mixture if necessary (working quickly is important here)

Now chill the tray of marshmallow in the fridge for at least an hour.

Then carefully slice the marshmallows to the desired size and coat them well with a 50/50 mixture of icing sugar and cornflour.

The marshmallows should keep well for a couple of days.

I hope you enjoy the recipe and it helps people to make some creative dishes of their own.



Methylcellulose Preparation -

Top prepare the hydrated methyllcellulose slurry you will need
Methylcellulose f50 or the Texturas Brand ‘Methil’.
Available from

6g Methylcellulose
400ml Water
Boil the water in the kettle then measure out 200ml of just boiled water.

Now blend the Methylcellulose into the hot water with a stick blender.

Next begin to cool this mixture over an ice bath while stirring intermittently until it is cool.

Allow this mix to sit for a couple of hours for the methyl cellulose to fully hydrate.

You can prepare this mixture in batches then keep it stored in the freeze indefinitely to defrost and use as needed.
