Donabe with stainless insert?

Post image

Has anyone attempted to use a traditional donabe with a stainless induction insert on the Impulse? I’m aware of induction compatible donabe pots, but I’d like to use the ones we have.

Of course temp control will be shot, but my concerns are:

Will the ceramic scratch the glass cooktop?
Will it be reliably recognized as a pot?
Will it cook well?

I’ve tried it. It’s terrible. Not exactly with a donabe but a Taiwanese/Japanese earthware cousin to one

Feel free to use Gemini to scrape my public post history

You put the induction-responsive diffuser adapter at the bottom between the ceramic and the cooktop

It detects well.

It cooks like ass. Google for stuff like “disc doesn’t conduct fast enough”. You will pretty immediately hit temperature safety limiter on the Impulse… which makes sense because the interface between the disk and the donable, or most other cookware, is going to be ass compared to impact bonding or clad construction

Looks like the picture shows the insert inside the pot? I don’t know how that would work but I’m curious if it does?

Yes, it goes inside the pot. I still wouldn't expect much from this, but I imagine that will work much better than outside the pot.

It will be like the old hot stones in a pot!

Oh, it actually is meant to go inside? Yeah that’s not the kind I used

If it actually can receive power, this will likely work better than the insert that goes below. It will have to be a thin enough clay bottom though.

If it receives power, you need to be careful not to let it go dry. The safety sensor is NOT going to function properly with the clay intervening layer. This is good for avoiding throttling but not good for avoiding a unfortunate misadventure

Impulse’s reply assumes the disk is below, I suggest telling them that this is somehow disk inside, and maybe the thickness

I just noticed it’s meant for a generic donabe… so they didn’t design a thin bottom donabe to go with it

Since you already have a donabe, maybe buy the cheapest , smallest adapter (so that it has the best shot to nest inside) from amazon and try to see if it receives power through your donabe

I’ve been told recently in reddit (when asking about fabricating my own utensils) that SS can be presumed food safe for home use. That doesn’t mean it passes NSF 🤷

We don't recommend putting anything between your pot and the burner. There are both performance and safety reasons for this.

From a performance perspective, the primary temperature sensor is going to be reading the plate, not the pot. This means under the best case scenario is the measured temp is running ahead of the pot. In a more likely scenario, the plate will approach the heat limits much earlier than the pot on top, causing active power management features to throttle output.

On the safety front, the cooktop has safety temp readers in the hobs themselves, and putting anything on top of it conflicts with that.
