I purchased her book a week ago and it is a must buy for anyone living in New England. It's a shame that I have many committments this weekend and cannot attend the symposiums you mentioned. I will say the Rotch-Jones-Duff House is a lovely place and a few fellow Gardenwebbers had a gathering there a couple years ago after a morning of plant shopping. I hope to catch Carol at another event and have her sign my book.

I hate mine. ive cooked on mine 3 times a day most days for about 2 years. Boiling water, soup, etc is not the problem unless you accidently boil something over — like the outmeal. Bigger problems are the skillets heat unevenly and it often shuts itself off. Try cooking an omlet and the middle is getting all toasty while the edges are still runny. even preheating the skillet does not completely solve this. When creating big family dinners with 4 burners out of my 5 are in use it often kickes off at a crucial moment in the dinner prep. I have to stop everything, remove all pans, clean the top, dry it and go again. i often dont see right away that all burners have kicked off for no apparent reason. All burners kick off at once. I bought expensive AllClad induction pans because I thought that might help and they’ve now all warped so that makes them cook even more unevenly. i believe they can’t take the uneven intense heat. Since I complained about the warped pans to my family I received another set of all clad non stick induction skillets for xmas and vowed not to heat them over medium. 4 months later they too are warped. I dream of the day i can replace my induction cooktop with either gas or electric. I’ve used both a lot and they get the job done a lot better. Mine is a Schott Ceran brand.

I can't tell from your photo exactly what you have, but it appears to be some version of the classic Jenn-Air cooktop (some of which were rebranded as Maytag, Whirlpool, or GE). Your specific model may no longer be manufactured, but they've made the same basic design since the 1960s and the cartridges/modules are interchangable between nearly all of them and remain readily available, so the new burner cartridges fit into most of the old cooktops and vice versa. All of them allow you to remove the grill and replace it with a two-burner module. Some also allow the burners on the right side to be upgraded to a smoothtop radiant module; but on others the burners on the right can't be removed. If you see a rectangular frame around them that's roughtly the size of the grill on the other side, your burners are in a removable cartridge. Lift the front or back of the cartridge and it will lift out. The currently available coil cartridge (JEA700ADB) looks like this: That is what your right side should look like if it's removable; if not, you can still remove the grill on the left side and replace it with one of these, which will match the general appearance of the existing coil burners on the right side. (the grill pops out and will have similar electric pins on the opposide side from the one you pull upward). Or you can upgrade one or maybe both sides to these A122B radiant burners, one 6" and one 8", which look like this: The only cartridges that won't fit are the wider "Expressions" ones with the electric pins on the left or right side of the cartridge rather than the front or back which they now call the "Designer Line" series. Also, if your cooktop is made by Amana it uses a different shape altogether. But most of these cooktops can accept both older and newer replacement cartridges. Used ones (and some new ones) are all over eBay and Craiglist as well. They used to make some styles they no longer sell, including halogen burners (A126 or A126B, my favorites) that turn on and off instantly, soild disk burners, and even induction burners which are hard to find and expensive if you do. Grills and griddles are also available. You just need to verify that the grill cartridge in your cooktop has the four electrical pins at the end (with a fifth unused hole) and that the dimensions are roughly the same. Another issue if you replace the entire cooktop with the Ikea one you linked to is that your existing cooktop has downdraft venting, so unless you also have an exhaust hood over the cooktop, you'll need to add a separate vent hood or a raisable downdraft exhaust behind the cooktop, as the Ikea cooktop doesn't have built-in downdraft venting. Anyway, find the model number (often under the grill cartrdige on a placard, or underneath the entire unit) and then you can be certain which new (or used) cartridges will work with your cooktop.

Hi @chefedwards, thank you for the detailed info on TPB and following through with updates. We are also located in the SF area, and my cousin and I are currently in process building two neighboring family homes and are considering TPB as well as Invisacook and other options for invisible induction for both homes. After reading through your thread and watching your video, our main concern is how loud the unit sounds in the recording. Is that just a function of your phone picking up those sound frequencies a lot, or is the TPB unit and pot actually buzzing and humming quite audibly when you use it in person? Would love your take on how obvious that is, and if it kind of makes the vibe of cooking a bit strange? Thanks in advance.
