My solution is to run the whole thing through some silicone air tubing from the pet shop. You leave the last few inches of the probe sticking out for an accurate reading, but the part that bends and the whole braid/wire part can be inside the silicone tubing. You just need a way to clamp it to the probe to seal it. Maybe some 100% silicone caulk would "glue" it. You can also use a piece of stainless lock wire as a twisty tie style clamp.
Silicone tubing is high temp rated. I wouldn't hesitate to dangle it into a boiling kettle.
