  1. I have been experimenting with reverse spherification with some success. I would like to try and "elevate" the technique and wondered if any one had tried colouring and / or adding flavour to the sodium alginate bath. I was thinking that would enhance the overall flavour and visual appeal. I know that with indirect spherification you can mix the flavourful liquid with the sodium alginate, but I'm wanting to keep the inside liquid so need to do reverse spherification. Does adding anything to the sodium alginate bath effect its gelling properties? I am curious that I haven't come across any recipes which suggest adding colour / flavour to the bath as that seems like a no brainer as otherwise the gel coating is kind of bland. I was wondering if that is because it doesn't gel properly when the Calcium doped flavourful liquid is dropped in.
  2. My birthday and XMAS both fall in the month of December, and typically I buy my own gifts and give to the kids / wife to wrap! This year I was looking at the two Madison Park cookbooks: "Eleven Madison Park: The Cookbook" vs "Eleven Madison Park: The Next Chapter, Revised and Unlimited Edition". Has anyone seen both to help me decide which of the two to get first? Are they sufficiently different that it might be worth getting both? And lastly the revised single volume "Next" cookbook I see from the description has 80 recipes whereas I believe the limited two volume signed edition had 100. Are the 80 chosen from the 100? Are the 20 "missing" recipes worth having? Thanks in advance!
  3. Hello, I have been reading this topic with great interest. Now that there are several owners / users of the Anova Steam Oven, I wonder if a consensus has been reached re the utility. What I am really asking is, Santa has requested my list and I would like to know it I should consider this as my big gift. (To be totally up front, I buy my own gifts and give them to either my wife or kids to wrap and give me!)
  4. Not sure what others mean by "bloody on the bone", but if they mean pink, the poultry could just as easily have been overcooked as under. The pink as I understand it can result from purple marrow which leaks from bone (especially from young birds typically found in stores which have more porous bone) and stains adjacent meat which will not fade regardless of temperature. Also from what I have read in Modernist Cuisine, cytochromes at a temperature of 80°C / 175°F loses ability to bind oxygen and turns pink. If you put the chicken in the fridge, the pink from the cytochromes rebind oxygen and pink decreases. Myoglobin is also pink and while it will turn clear with cooking, the temperature at which it does is variable so it can not be used as a measure of doneness. Bottom line, don't worry about the pink, worry about the temperature!
  5. Thanks for your thoughts. You are correct; he was simply prehydrating. I had asked him how he managed to create such a nice texture as in my experience I could never adequately hydrate the Xanthan. That's when he wrote out the ratio to create the Xanthan goop. What he would then do was take a small amount of the "goop" ie prehydrated xanthan gum and add to the liquid to reach the desired consistency. I think you can get a sense of the consistency he was achieving with the addition of a small amount of the goop from my pictures above. It wasn't snotty at all, although I have on too many occasions over thickened sauce with xanthan. But even prehydrated, I have had difficulty incorporating the xanthan goop into the liquid to achieve a smooth texture. As for the green, I was hoping I wouldn't have to wait for St. Patricks Day to get a Shamrock Shake if you think that is the secret to the green! Surely there is another option?
  6. Thanks for suggestion! Will read MC of course, but I found one new copy of this book at Amazon on sale... couldn't resist! Should arrive by Feb. 1st.
  7. I have to admit ignorance on this and had to google it! Is this what you are talking about? https://en.wikipedia.org/wiki/Homogenizer. Looks like a very cool device. Do you have a specific one you like that is appropriate for the kitchen? Mechanical or sonic?
  8. Maybe you can share some of your blends ratios and when / how you use them? I was going to actually create another topic on the subject of blending and using hydrocolloids, but since you brought it up here: Despite reading on-line resources including the excellent Kyhmos recipe collection ( https://blog.khymos.org/recipe-collection/ ) and Dave Arnold's hydrocolloid primer ( http://www.cookingissues.com/index.html%3Fp=1247.html ) I remain confused because it seems you can use multiple agents alone or in combination to create different or the same textures. I haven't gotten to the section in Modernist Cuisine on Hydrocolloids (trying to read all 5 volumes in order and am only part way through V3!) so maybe some help there, but I would love it if there was a chart that rather than listing the Hydrocolloid and what it does, the chart list the effect one wants to achieve and then the agents needed to create it. For example, Stabilize sorbet - use xxx, Thicken cold sauce - use yyy, Create liquid filled spheres - use aaa + bbb. etc. rather than having to read through all the hydrocolloids as in xxx- used to stabilize sorbet, yyy - used to thicken cold sauce, aaa - can be used with bbb, bbb - can be used with aaa. Hopefully you get the idea and it isn't dumb or I have missed some resource that already does this! Lastly, I have lots of individual hydrocolloids sitting in my larder, but I keep coming across recipes that will call for a specific brand, e.g. Sosa Vege Gel (carrageenan, carob, etc.) and it would be nice to just blend your own!
  9. I am very fortunate to have a vacuum chamber which I have used for this very purpose. Haven't quite figured out best way to do so though. Do you like to create vacuum and when liquid about to boil over immediately release vacuum, or do you hold it at that low pressure for a time then release vacuum? Regardless of the two methods, do you do a fast release of vacuum or slow? Or does it matter as long as you don't boil liquid over creating mess in chamber?!
  10. Largely because starches can effect flavour and clarity. As well hydrocolloids have other properties one can make use of, e.g. forming different types of gels etc. https://www.cooksillustrated.com/science/859-articles/story/word-of-the-week-hydrocolloid
  11. Thanks. I was thinking the same thing about the particles in suspension. I was amazed though at the vibrancy of green and was wondering what he used. As for the stick blender or vita mix, I usually don't have enough volume to make those particularly effective, which was why I was so hopeful the pre hydrated xanthan would allow me to more easily incorporate it into a small volume of liquid. I guess I just need to be more aggressive with a hand whisk?
  12. Thanks for the info. Can I ask, is the pre-hydrated ratio the same, 640ml of water mixed with 27gms xanthan? And how small / big amount of "goop" would you use for example with 250ml of liquid? Also, does heating help?
  13. Hello, I had the opportunity of dining in Munich at Chef Jan Hartwig's three star Michelin restaurant Atelier. The food was delicious and the plating gorgeous. Several of the dishes made use of a "sauce" poured at table side which I have been trying to recreate. I have attached photos of two of these dishes. Unfortunately I cant for the life of me remember the flavor profile (too much wine maybe and too long ago?) but I was hoping some help might be forthcoming from all of you! I asked chef how he created the viscosity and he indicated xanthan gum to which I replied I always had difficulty hydrating it. He shared his secret; hydrate in advance and add to the liquid. He says he uses 640ml of water mixed with 27gms xanthan. This can be stored in the fridge until needed. You then take some of this gloop (at least that what I ended up with!) and add to your base liquid. Questions: 1) Has anyone tried this pre-hydration of xanthan and if so, how do you use it? Best way to mix? How much to use? etc. As noted, I ended up with a goop that was just as hard to disperse in my liquid as just using powdered xanthan. 2) Any ideas as to what the "green" is in either of the two dishes? He makes use of it frequently in other platingsI have seen he posts on his instagram and his facebook pages (Jan Hartwig - Restaurant Atelier, München). 3) What are or causes the "speckles" in the two different green sauces? Thanks in advance!
  14. Just measured: Bottom of chest freezer exactly -20C / -4F
  15. Thanks for noticing. I think I mistyped and meant Centigrade! -20C = -4F -22C = -7.6F So if home freezer -18C / 0F, that would make Pacojet use in a home environment problematic if the temperatures I understand are required are correct.
