65⁰ for the perfect egg?

Can you cook a perfect egg?

Can you cook an egg? It is harder than one thinks to cook a (near) perfect egg. The film Julie and Julia that we are currently enjoying makes the point firmly, to learn cookery one starts at the beginning, cooking eggs.

This eggs / 65⁰ eggs

For some reason, although we have had the sous vide circulator for a while now, and use it frequently when cooking meat, I have not before tried the famous 65⁰ egg. It should probably be called the ‘This Egg’, or «Œufs This» since this temperature is the result of work by French molecular gastronome Hervé This.

So for today’s experiment I am making myself a couple of 65⁰ eggs. The sous vide is the ideal way to do this, avoiding the terrible error of 64⁰ eggs.

During lunch at a local bistro, I notice a 65-degree-Celsius egg on the menu, served on a fricassée de girolles. As the plate is set down, This says: “That’s not a 65-degree egg. It’s a 64-degree egg.” The yolk is soft, and the egg white, while completely opaque, is so delicately jelled and fragile that it breaks apart slightly when it is plated. “Eh, oui,” the chef sighs; he is having des ennuis regulating the heat of his stove.  (Quoted from Discovery)

According to This’ research at 65⁰ one gets soft creamy yet set whites and a soft not quite runny yolk, pretty much how I like my eggs. For Barbara I may have to do some 67⁰ eggs, but today is about me 🙂

As the featured image shows, my 65⁰ egg is as described, the whites are opaque (though only just) and are indeed creamy, and as promised a ‘revelation’. The yolks, however, are almost set, and so for me less than exciting.

The quest for my ‘perfect egg’ continues…

This only cooks his eggs a short while, that might be the answer, but the Chef Steps egg calculator suggests that the perfect egg for me with a pretty firm white and yet pretty runny yolk would use 75⁰ for 15 mins or, after 12 mins ice and reheat… I may try that tomorrow.


PS, these This Eggs were topped with a lemmony mustard mayonnaise, but does anyone know a quick easy foolproof way to make hollandaise?

Gelification: or edible pearls

One of the simplest Molecular Gastronomy techniques is cheap yet powerful. Gelification simply means turning something into a gel. Your mother or granny (or come to that the people who cooked your school/hospital/prison dinners) used gelification if only when making jellies (what the Americans call Gello).

This post will introduce the fun and delicious results you can get through gelification by making edible pearls.

What you will need

Juice (I used commercial beetroot and purple carrot 1 This commercial juice is sweetened with apple juice, so I’ll use the pearls as a decoration/sauce for roast pork. but I have also used orange and lemon, and balsamic vinegar pearls are really fun for brightening a salad – almost any liquid you can eat can make edible pearls)

Agar agar sounds complicated but you can buy it at many Asian stores, some supermarkets, or online from stockists like Equagold.  2 $16 sounds expensive for a mere 60g, But that will make 60 times the quantity I used for Barbara and me, and if your local stores have it they will be much cheaper.

Vegetable oil (I used rice bran, posh people use Extra Virgin Olive Oil, I will when I am making pearls to dress a salad, but for this I plan on washing my fruit pearls).

Dropper or syringe look around a little and you’ll find droppers or syringes available cheaply (I’d try your local plastic box shop or $2 shop).

Tall glass or jam jar the taller and narrower the better within reason.


Put the oil in the glass or jar (not too full, you need space for the juice) in the freezer for about 30 mins (some oils like olive need to be watched, so they do not set to solids) others can be left much longer.

Take juice and agar agar. Half a teaspoon (2.5g) of agar agar will set one cup of juice, I did half that for decoration/sauce for two people.

Sprinkle the agar agar on top of the juice in a pan, warm till just bubbling, stirring as needed.

Dribble the hot (as near boiling as is comfortable) juice 3 Agar agar sets at 32-40⁰C but only melts at 80⁰C into the oil. Enjoy watching the pearls form as they drift to the bottom of the glass. As in this video:



Coming soon: gelification recipes and suggestions, starting with a Vegan crème brûlée with citrus pearls.

Molecular Gastronomy (simple and cheap)

This new series Molecular Gastronomy (simple and cheap) makes molecular recipes simple: explaining the techniques without mystification or complication. It also aims to let you try Molecular Gastronomy at home on a budget.

Molecular Gastronomy is a silly and complicated name for having fun with cooking and eating. After all, molecular means ‘to do with molecules’ so basically chemistry and physics. Gastronomy means to do with the science and art of cooking and eating. But all cooking has to do with using chemistry or physics (or more often both) to change the food we eat. The only gastronomy that is NOT ‘molecular’ is preparing and eating raw food!

So this series will introduce ‘Molecular Gastronomy’. We’ll keep it simple. We’ll also avoid expensive equipment (as far as possible) and complex kits. Other sites offer great kits and impressive gadgets. Here we want cheap Molecular Gastronomy.


Coming tomorrow: Gelification: edible pearls will describe a simple cheap Molecular Gastronomy technique to add bursts of perhaps surprising flavour to your cooking.

New life for an old blog?

This blog has been moribund, the reason is a mix of pride and shame. I am proud of having adapted to living on a lifestyle block, and of caring for animals (cattle, sheep, and pigs) fairly successfully as well as growing fruit and veges (with rather less success as we are at 400m and enjoy cold winds which carry passing clouds across the property). But this combination means we have been far from the ideal of repentant carnivores, rather we have been eating lots of/too much meat, because that is easy and cheap to grow ourselves, while cabbages are harder work, and beans or lentils must be bought from far far away. Being a locavore and living here implies being an unrepentant carnivore.

However, I have a new interest, molecular gastronomy (a horribly pretentious and often inaccurate name for having fun using the science and art of food to produce food that is delicious or entertaining in often surprising ways).

Like many who are intrigued by Heston Blumenthal, or today our local restaurant, producing foams, pearls, ‘caviars’ and the like, I dreamed of doing the same at home. When Scripture Union gave me a generous Prezzie card, as well as the joy of seeing kiwi in the wild. 1 So, I treated myself to a ‘Molecular Gastronomy Kit’.

I’ve begun to have fun with it. I am sold on ‘molecular gastronomy’ at home. But as well as the silly pretentious name (which we now have little chance of changing), the high cost of entry (both in money and in time) seems unnecessary. So I plan a new section for this dying blog, Molecular Gastronomy (simple and cheap). I plan to show you in a number of simple steps some of the best techniques and point you (especially Kiwis who do not have the same access to specialised stores) to cheap sources of equipment and ingredients.
