Sous Vide with Butter

Hello!

I'm new here, I've got a copy of Modernist Cuisine at Home, finally got an immersion cooker and starting to explore. One thing I was curious about - why is it not recommended to cook sous vide with butter for extended periods of time?

Hi @Sky

From my

personal experience;

At low temperatures

butter clarifies. Butter melts at 36 °C

, separating milk solids as lacto protein,

Milk sugar and water from the butter fat, this could affect the taste of the package

content.

Manfred -

The caution against using butter always seems to have a time component to it - 4 hours or less if I remember right. Definitely anytime butter is melted it'll separate, just wondering what the time issue is.

Beurre monté will remain emulsified....especially "bulletproof" beurre monté.

I intend to experiment more with beurre monté in sous vide applications when i can find the time.

@diggingDogFarm - Thanks for the link to the beurre monte on the Ideas In Food blog. I somehow missed that one.

I made it last night and it worked like a charm. I added it to a zippy with some mahi mahi that I cooked in a water bath at 52C for a core temp of 50C and then a quick high temp sear to color. Just fantastic...
