I’ve been thinking about sous vide cooking, reading about it, and I’m finally going to try it, especially since it CAN be done without any fancy equipment–except a beer cooler. That I can handle–in fact, I already have one–I just had not thought of it as a kitchen appliance.
I’ve been wanting to try sous vide cooking, especially reading about it Stefan’s Gourmet Blog posts. Being somewhat budget conscious, I’ve explored alternatives to the water ovens and circulators usually used in sous-vide cooking. I’ve looked at articles on how to turn your slow cooker into a sous-vide machine and discovered that requires some additional equipment and “hacking” to work; that’s also not for me.
There seem to be a lot of reasons for using this technique, not the least of which is to avoid heating up the kitchen and overworking the A/C! There’s also the appeal of the evenness of cooking and not being able to overcook unless you give a lot of attention to the actual cooking. All those advantages and some alternatives to expensive equipment or ones that require engineering know-how at least let me try it. One alternative I discovered was a big pot of water, low oven temperature–not an option in summer for me. I found references on adding external temperature controls to rice cookers and multifunction pots, using the oven, and, of course, lots of ads for sous vide tools.
So what has precipitated this sudden fit of actually doing it? It’s the hot, muggy, humid, steamy weather we have here in the summer and the fact that I’m a serious fresh-air freak. If it’s at all possible I’ll have the doors and windows open–Frankie especially appreciates this. I want to cook without having all the extra heat–so I’m exploring all possible alternatives, including adapting recipes that normally involve using the oven for the slow cooker–looking for ways to beat the heat.

For food safety temperature is important so I looked at lots of articles giving temperatures for various meats and fish, including on that considered using the keep-warm function on the rice cooker or multifunction pot. Next to the beer cooler method this looked like a possible one for me since I do own a Krups multifunction pot. To check that out I filled the pot with and checked the temperature on the slow-cooking setting–the temperature held at 185 ºF which looks as if it might work for some veggies and, perhaps, for tough cuts of meat. Switching to the keep-warm function and doing a temperature check two hours after I had switched to keep-warm function–but the water started at 185 ºF and I had absolutely no information on what the rate of cooling in the closed multifunction pot was. So–more data, please! I started with water at 110 ºF on keep-warm setting to see what happened. What happened was 165ºF.
So the multifunction pot (Krups) is out for just using the warm function, but I’ve discovered that if the pot is hot and then turned off, it hold a steady temperature for about two hours. Since I’m only doing sous vide for one and quick things, I don’t need a huge pot. This is going to take a bit more tending, but it would certainly be easier for quick things than a beer cooler (my laziness is showing, I know).
Searching for the best temperature to use for monkfish sous-vide produced an interesting array of suggestion. Always preferring data, I was glad to see Monkfish sous vide temperature experiment which tested throughout the range of temperatures that I found and gave a description of the fish texture at each.
From ChefSteps I also found the following temperature guide for fish and from Amazing Food Made easy temperatures and times in the range of 10 to 30 minutes:
- Tender 40ºC/104ºF
- Tender and flaky 50ºC/122ºF
- Well done 60ºC/140ºF
For my monkfish, I think tender and flaky is a good option; for tuna, I might go for just tender–or even rare, depending on the grade. Now for time specifically for monkfish to be medium the general consensus seemed to be “medium” at 140ºF for 10 to 30 minutes. Since my tap water is at 140ºF with the beer cooler I should be good to go–though it seems strange to not have to be concerned about time but since it won’t go above the water temperature anything in that range should work.
For seasoning? Well, simple seemed good for my first try so I went with salt, freshly ground black pepper, and butter. I used the rice-cooking mode to bring the water up to 140ºF, put the monkfish in, closed the lid and crossed my fingers. It just seems too simple even though I’ve cooked other things by putting them in liquid and then turning off the heat and letting the residual do the cooking.
The results? The best monkfish I’ve ever eaten. Okay, so I’ve not had anyone else’s monkfish cooked sous vide, but it’s the best monkfish I’ve ever cooked. I cooked it at 140ºF for 30 minutes. Temperature check at the end of the cooking was still at 140ºF. The fish was tender and just starting to flake. I’m still trying to find some adjectives for it. If i have to pick one I think it will be just plain luscious!
Now that I’ve done all the temperature experiments on the Krups multifunction cooker (in slow-cooking mode and keep-warm mode), and on how it holds temperature, I see more sous vide in my future.
