edit: and despite what Rubycon posted, I frequently have students who claim they were the best tasting hotdogs they've had in a long time. No "funny" taste to them at all, unless there's arcing at the electrodes (nails)
You should use platinum wires for best results. 316 stainless steel is an adequate substitute.
If you can you should repeat the results with higher voltage.
The brand name may have influence as well. I have not done this in years.
I've burned various foodstuffs with lasers but it just ablates the surface and makes holes in it.
Never ate anything from these type of experiments either because of the severe charring.
