Sunday saw my third attempt at sous vide, the first two being somewhat flawed (see note below). I wanted some tender and deeply flavored shrimp. And I have a FoodSaver
. So, into the vacuum we go:
Ingredients:
1# shrimp, peeled and deveined
4 oz butter
1-2T fresh rosemary leaves, slightly bruised and rough chopped (dry rosemary is fine, too)
2 cloves garlic, minced
Method:
1) Place all ingredients into Foodsaver bag and vacuum seal. Refrigerate until ready to cook.
2) Using a candy thermometer, heat a large pot of water to 138ºF. Get temperature to a very stable state prior to putting Foodsaver bag in.
3) Place Foodsaver bag in pan and cook for approximately 12-15 minutes. To judge doneness, note the color of the shrimp, just like you would using any other cooking technique. You will also be able to feel a difference in the shrimp, though since they stay so tender, it will not be as pronounced a change.
Notes/Results:
+ This was amazing. The shrimp took on a beautifully tender texture and a gentle infusion of both the garlic and rosemary. Great for an appetizer or as a garnish item. Or toss the shrimp and the butter with some pasta and a nice parmesan.
+ It's fun watching the shrimp cook and the butter melt.
+ While the temperature would require more careful monitoring (unless, that is, you are using an immersion circulator), larger batches of shrimp could be done this way, making for an easy and hard-to-ruin way to prepare them.
+ I used (and highly recommend) Vermont Butter & Cheese Company Cultured Butter
+ Next steps: attempt this with other proteins, especially seafood, and other cooking liquids, such as cold consommés. (I am way too excited about what you can do with the cold consommé technique).
+ Rather than limiting this to a cooking technique, why not also use it as a flavor infusing technique for pantry items such as compound butters? Throw the herbs and butter for a nice long soak in their vacuum bag -- then cool and reshape.
+ For the curious, the first two sous vide experiments were #1) beets with a bad seal on the vacuum bag and 2) carrots that, while good, weren't cooked to the proper degree of doneness.

Someone asked me why 145ºF? It was a desire to play it safe. While I know that many cooks have had great success with sous vide, the method does create an anaerobic environment, much favored by clostridium botulinum. Since I knew the cooking period was going to be short and resultantly, the time under vacuum equally short, I thought this time/temperature combination to be safe. If storage of the product is involved, the food safety measures would have to be more stringent.

After doing this numerous times, I have been backing off on the temperature. I now do this at 138ºF. The shrimp cooks pretty quickly, even at this temperature. You should make you own best decisions about such things -- just letting folks know what I have tried. Another tip: to help getting a good seal, make sure that you have toweled-off the shrimp prior to putting them in the vacuum bag. Also, you certainly need not use the amount of butter I have; I just like having the shrimp/garlic butter when I am done.
