Blood Emulsification?

Hello. I'm new to this forum and to emulsions. I've made a few dressings lately, but that's about it. After doing some short ribs in the sous vide machine I was wondering if it is possible to make an emulsion of the blood you strain off the ribs by adding a little egg or mustard and using butter as the fat. And if not, what is the blood lacking that prevents this process? Thanks in advance. Sorry if this is a ridiculous question.

Jason

The liquid is not blood. It is primarily water and myoglobin, the protein that gives meat its color.

Jason, I'm not sure I understand the context of your question. Are you trying to make a sauce of sorts for the meat, or something else? Maybe just me, but I wouldn't use meat juices for salad dressing, if that's what you're asking.

In short, no.

That juice is the same liquid that seeps from frying meat to create fond in the pan. It has lots of flavor, and can be solidified and made crispy by adding it to a hot pan while frying meat. When the pan is de-glazed, you have a broth that can be used in gravies and sauces. Most people throw it away. I don't. I know, I'm strange.

Jeepers Creepers.

Seems everything requires a license these days.

Yes, I'm trying to make a sauce for the meat. But as I'm also trying to learn a little bit about emulsions, I'd like to know if I can use that method to thicken this liquid. And if I can't, why not? Thanks

I've never done sous vide - how much of this liquid is left after cooking? You need a fair amount of water-based liquid to make an emulsion.

I suggest you try it and see what happens Let's say you have 1/4 cup of liquid. You could sear the ribs in a pan after the sous vide cooking, then deglaze the browned bits with the liquid; melt 1/4 cup butter in the liquid, then whisk in 1/2-1 tsp. mustard. This would give you about 1/2 cup of an emulsion. Taste and let us know what you think

I cook sous vide all the time. The liquid that you drain out of the bag is not rich and flavorful. It's thin, watery and very greasy. If you've seasoned your meat well before cooking in the water bath, the liquid is also very salty. Once reduced, it's pretty inedible. It does not make a good sauce. If you insist on trying to use it, pour it into a cup and let it sit until it's cool, then remove the fat.

It you want to make a reduction sauce after sous vide, pat the meat dry, then quickly sear it in an extremely hot cast iron skillet with just a little fat. You only want to sear - not cook the meat any further. Then deglaze the pan with some wine or stock (or your leftover liquid) and reduce. If you want to learn about emulsions, off-heat swirl (don't stir) cold butter into your sauce.

Or ..... make mayonnaise. It's the perfect lesson in emulsions.
