I have a slotted turner (cookery) with a thin stainless steel

Id like to replace the handle, but that requires a material
that:

* is D-I-Y workable
* has low thermal conductivity
* resists exposure to high temperatures
* is dishwasher proof

any suggestions?

Yup. You probably want a cold cast resin of some sort.

Oven cured.

Being a bit of a hand worker I'd use car body filler to make a
lumpenhandel and then file it down to whatever shape is acceptable.
Then a pigmented coat of polyester over the to and polish to a nice finish.

Unfortunately the brief research I did suggest that temps over 100C
might be the end of polyester resins so epoxy rears its ugly head.

Possibly your easiest route to one of those with a suitable pignented
filler in might well be Milliput.

As with all epoxies, mix exatlyly identical quantities really throughly
and stove the final thing in an oven at around the 100°C-120°C mark for
much faster setting and much harder result.

Milliput can be sanded and polished once set for a pro finish.
