At the same time I heard about a book from Spanish cooks called Joan Roca and Salvador Brugués. But this book was available in Spanish only. This book is now available in English and French. The price of this book is crazy! I saw some online shop proposing it at USD 200! I bought mine in French language at EUR 110 incl. shipping.

The book is nice and full of technical information (100 pages of tech. information to be compared with 50 pages of recipes). I didn’t have time so far to read it completely but one think already disappointed me, you cannot find cooking tables such as Baldwin ones. If you want to cook with Joan Roca and Salvador Brugués cooking book then you need to purchase some turbigomme and a penetration probe…again. Anyway this book seems very interested and I’ll give you my feed back soon about it.

I have experimented Baldwin tables for a while now and I have to admit that I have never been sick or disappointed by the degree of doneness according to the temperatures given.

Nevertheless I realized that nobody on the net ever discussed if Baldwin tables are correct or not. Do I have to accept the fact that everybody is assuming these tables are accurate?

This the reason why I decided to purchase an external penetration probe and verify by myself. For those who would like to purchase such equipment I want to say that I made a mistake in my previous post when buying the needle probe from Thermoworks. The one that should be used for sous vide (water proof) is THS-113-181 only (see on the right of the picture). The needle is very thin (1 mm) and long enough to get inside a 7 cm thick beef fillet (incl. the turbigomme foam).

For my first test of Baldwin table I took a cut of salmon, 30 mm thick that I wanted to cook “mi-cuit” at 47°C. Douglas Baldwin table indicates 1 hour and 2 minutes cooking time. As mentioned in Baldwin document I raised the temperature of my immersion circulator of 0.5°C (47.5°C) in order to be sure to reach the target temperature of 47°C.

In order to comply totally with Baldwin table I took care the core temperature of the salmon was 5°C. This step made me realizing that my fridge is definitely not cold enough as the core temperature of my salmon was 10°C before chilling it! As illustrated on the picture I immersed the pouch in iced water for some minutes.

As mentioned above I set my immersion circulator at 47.5°C for 1:02 and noted frequently the data in order to make a graph out it.

And the result is EXCELLENT!

I was very surprised to see how fast the temperature was raising during the first minutes. I was also having some doubts when the countdown of my sous vide equipment was indicating 22 minutes left while the core temperature of the salmon was 36.6°C. The last tenth of degrees take really long to be reached and I now understand why you should set your sous vide appliance 0.5°C above the target temperature…if you don’t it will take ages before you really reach the target temperature.

Today Polyscience made the demonstration that a non stired water bath cannot be as efficient as an immersion circulator. It is funny to see that Polyscience directly mentions Sousvidesupreme in the TAG of the article.

Polyscience video indicates clearely that a non stired water bath has a longer response time to reach the desired core temperature. Therefore, it is obvious that Douglas Baldwin cooking tables sould be used with care. Douglas Baldwin indicates in the Pratical Guide to Sous Vide “With all these digital controllers, I highly recommend setting the temperature offset (measured near the temperature at which you wish to cook) using a high quality digital thermometer. Indeed, at the default settings the thermistors used in the above controllers can easily be off 2–4°F (1–2°C)”.

Freshmealsolutions mentions clearely in the user manual of the SousVideMagic : “If you don’t have a proper food core temperature sensor probe, always cook at desired core temperature settings for the duration as specified by reliable recipes with an additional safety factor of at least 25% longer…”
In addition the manual indicates “The default settings are designed to overshoot 1 or 2 degree higher for safety reasons. You can reduce the overshoot by making your own PID adjustments. See the document “PID Tuning”.”

Today I woke up and decided to “swid my salmon”!
I purchased 2 pieces of salmon, 20 mm thick, seasoned them with salt, pepper and a little bit of frozen olive oil.
A common problem when cooking salmon, is that the protein albumin leaches out of the fish and coagulates unattractively on the surface. Therefore I brined the salmon 10 minutes in a 10% salted water.

I had look to Douglas Baldwin table about temperatures & times for pasteurized and “mi-cuit” salmon.

Pasteurized salmon (20 mm thick):

55°C         57.5°        60.5C
4:20        1:52            41′

I decided to cook 41 minutes at 60.5°C

Salmon “mi-cuit” (20mm thick):

Very Rare          Rare Medium Rare          Medium Medium Rare
38.5°C                        47°C                                      52°C
26′                               28′                                           28′

The albumin was very present at the surface of the pasteurized salmon. The “mi-cuit” salmon had really less albumin and I could easily take it off before searing it.

(very few albumin appearing on the “mi-cuit” salmon)

I seared the salmon in a pan with a bit of olive oil.
As you can see on the pictures the difference of colour between the pasteurised and the Medium Medium Rare salmon is not obvious.

(left, pasteurized salmon – right, “mi-cuit”)

To sum up I would say the salmon “mi-cuit” 52°C cooked during 28 minutes was definitely the most flavorful. Next time I’ll try both “mi-cuit” 47°C and 52°C during 28 minutes.

Good news for sous vide enthusiast who are not comfortable with the English language. Douglas Baldwin “Practical Guide to Sous Vide Cooking” has been translated en French and German by Addélice. This guide is therefore available in 4 languages (incl. Portuguese).

We are also waiting for the launch of addélice immersion circulator (the Swid) that should be vailable in some days (addélice postponed several time the launch of the Swid but told me some days ago that it should be available within one week. For the record, the Swid should be at EUR 449 incl VAT and sending costs!

I was very attracted by the design of the Frisper when I saw it for the first time. The vacuum machine from Oliso is definitely a very cute and compact device.

You know my philosophy now …if I see something new, you have to try it!

First of all lets make a fast comparison between the LAVA 100 vacuum machine I purchased some months ago and the Frisper from Oliso. The LAVA 100 is a powerful appliance with a “safety box” but its price is 3 times the price of the Frisper (EUR 245 to be compared to approx. EUR 80). On the other hand the Frisper is really less powerful than the LAVA 100 and the price of the specific plastic pouches that must be used with it is significantly higher compared to “normal pouches” (without any zip). Pouches can usually be purchased in the range from EUR 0.11 to EUR 0.50 (if purchased in a pack of 50 or 100 pieces). Plastic pouches used with the Frisper can be sold in a pack of 20 bags for a price of approx. EUR 1 per bag. These bags a theoretically re-usable 8 times but this possibility id useless in the frame of sous vide cooking as bags should not be re-used for food safety reasons.

Therefore the main question is “can the Frisper vacuums enough for sous vide cooking purposes”. Please have a look of this previous post illustrating their is no need of a professional vacuum machine to cook sous vide.

I confirm the Frisper is good enough. For my try I took 2 chicken legs (35 mm thick), added a little bit of marinade, vacuumed them with the Frisper and cooked them at 66°C during 75 minutes.

Last time I cooked chicken legs sous vide (30 mm thick) I decided to comply with Douglas Baldwin time and temperature table (64°C during 60 minutes). The result was good but a little bit bloody on some parts. Click here to read the post mentioning that point.

This time I have decided to raise slightly the temperature and the cooking time.

The texture was again very good and the chicken not bloody anymore. Nevertheless the chicken was still a bit too pinkish for my girlfriend taste. I guess next time will be the good one.

In order to compare with the bloody chicken leg I cooked during my first experiment, find bellow a picture.

This is my first try with cooking shellfish sous vide : a lobster tail.

I looked at Thomas Keller’s time and temperature table which mentioned a cooking temperature at 60°C during 15 minutes for a lobster tail. I am realizing more and more that Baldwin’s Sous Vide Guide is very practical. The information about the thickness is key. Douglas Baldwin indicates a 20 mm shellfish is pasteurized at 60.5°C at the condition being cooked during 41 minutes. I have decided to follow Douglas’ recommendations.

I took off the shell and seasoned the lobster tail with salt, pepper and a frozen teaspoon of  “extra vierge” olive oil. After cooking I seared the lobster tail some seconds in a skillet with some olive oil.

The result was very good. The flesh of the lobster was moist and had a very pleasant flavour of olive oil.

Another successful try!

I am just coming back from summer holidays and unfortunatly I’ll have to give back my Jubalo EC immersion circulator next week! Sniff!
In the meantime here is the result of my first try of cooking sous vide chicken legs.

I saw on Twitter a post from 3beanespresso who was asking himself why his try of sous vide chicken legs at 66°C for 38 minutes was leading to a gory result http://twitpic.com/fo3tl.
There was a long time that I have not looked at Douglas Baldwin “A Practical Guide to Sous Vide Cooking”. I realized 3beanespresso used Douglas table. I therfore decided to try myself 64°C during 60 minutes (on chicken leg was 30 mm thick and the other one 35 mm).

I found on the net a recipe for the marinade :

• 1 tablespoon minced ginger
• 1 minced garlic clove
• 3 tablespoons Hoisinsauce
• 1 tablespoon hot chili sauce
• 1 tablespoon dark soy sauce
• 1 tablespoon honey  
• 1 tablespoon water

I took the chicken skin off and immersed the chicken legs 3 hours in the marinade. Then I took off most of the marinade surrounding the chicken before vacuum sealing the chicken legs. This way I have avoided leakage of marinade inside my non profesional vacuum sealer machine. I think next time I’ll freeze the marinade.

After cooking I seared the poultry some secondes with my blowtorch and a little bit of oil, just to make the chicken looking more appetizing.

The result was fantastic! I could realy feel the marinade and the chicken was moist and perfectly tender.
The 30 mm chicken leg was not bloody except some little red parts located close to the bones.
The 35 mm chicken leg was globaly a little bit more bloody than the 30 mm one (see the picture bellow) but the texture and the flavor were still fantastic!

I will definitly try again this recipe and next time add 10 minutes more to the time indicated in Douglas Baldwin’s table.

• gathering information, books, identifying internet sites of interest,
• a vacuum machine,
• a digital thermomether,
• a device that enable controling very precisely the water temperature.

Those last days I worked on the 2 first points. I purchased the Sous Vide cooking book of Viktor Stampfer (Sous vide – Garen im Vakuum- Cooking in a vacuum - Ed. Matthaes) € 68 in a bookshop. It is a lots of money but I think this is worth it to start on good basis. I also read with a lots of attention the excellent “Practical Guide to Sous Vide Cooking” of Douglas Baldwin. I’ll make some summaries of this document later when necessary.I also looked carefully at vacuum machines. There are thousands of trademarks of vacuum machines and it will be totally useless to compare prices (in the range from € 150 to € 2.500 for professional machines!) and specifications. Therefore I asked for a friend of mines’ advice who told me the German LAVA products had excellent reputation. Then I purchased a LA.VA V.100 for €259. I have a trick for you. If you buy this product from the German site you can benefit from a special offer (2 acryl containers that can be vacuumed and 50 vacuum packing bags of 25×40 cm) that represent a discount of approx. € 50. I should receive this machine soon.
