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.

No need for a professional or powerful vacuum machine for sous vide at home

by on Jul.12, 2009, under Equipments & Accessories

sous_vide_cooking_org_cookery_equipment_vacuum_machine_cookingissuesWhen I started cooking sous vide I had difficulties to decide which vacuum machine to purchase. Finally I bought a non professional vacuum machine (Lava 100) which is powerfull and high quality made. This vacuum machine was a big investment  (EUR 250) for my student budget.

When surfing on the excellent CookingIssues.wordpress.com site I found a very interesting post about vacuum machines affecting textures of ingredients (click on the image bellow for a direct link to the post).
To sum up this post I would say that there is no need of a powerful vacuum machine for vegetable, fish and poultry (such as chicken). CookingIssues even says that for some ingredients such as chicken, the more you increase the amount of vacuum the more you affect the texture and the flavour! On the other hand CookingIssues did not mention any drawback regarding high amount of vacuum for meat.

Just to say that sous vide cooking at home is definitely possible with a cheap vacuum machine. Remember that the issue consisting in sealing sous vide a marinate can be solved by freezing the marinate.
