Question #1: When did you first learn of sous vide cooking?

In 2002 I heard about the immersion circulator method while working in California. A chef friend mentioned that Thomas Keller was using laboratory equipment (a PolyScience immersion circulator) for cooking butter poached lobster. I then tried to imitate that technique with a pot and a thermometer. 
There are quite a few old-schoolers in Switzerland who took part in Sous Vide experimentation in the 70’s and as a result, vacuum-packing fennel and then cooking it in a combi-steamer became standard practice. These recipes are taught in culinary schools and apprenticeship. At the time I was not particularly amazed. I only began to understand when I ordered my own circulator in 2010.

Question #2: What sous vide equipment do you use?

I distribute PolyScience products and teach Sous Vide workshops. Therefore, I usually keep 3 PolyScience Chef Series and one Classic Series at hand. I also have two Anova Precision cookers for testing the bluetooth connection of the Sous Vide °Celsius iOS app. I use chamber vacuum sealers by ERME Swiss vacuum technologies and Thermometers and probes by ETI temperature instruments.

Questions #3: What was the first thing you ever made sous vide?

Fennel. Lobster. Upon receiving my first circulator, I tried poached egg at 62°C for 1 hour.

Question #4: What was your biggest sous vide mistake?

I constantly make mistakes. The problem is usually that I cook things too long or too hot. Beef shoulder at 58°C for 96h, is a dry mess. Goat leg at 60°C for 48h. Besides looking ugly, the meat falls apart when trying to finish it on a grill. A few too many bay leaves in a 32h pork neck, taste gnarly.

Question #5: What was your biggest sous vide success?

I enjoy introducing people to the technique. It makes me happy to share the excitement and be helpful to others. Eggs, egg based emulsions, fish, steaks — they are all good. Naturally, I am fan of ribs, cooked long and slow. And vegetables too. I remember this event where I handed out Sous Vide carrots. Young carrots, that had been picked from the garden. You had never tasted a carrot like this before.
One clap, two clap, three clap, forty?

By clapping more or less, you can signal to us which stories really stand out.
