Best way to de carb hash?

Hi I have an excess of import hash and i want to make edibles. I am a season vet with edibles and want to make something high does. Anyhow I've asked before and I get a mix of 240f for 30 mins and than some say 40 mins. Some also suggest just decarbing it in a frying pan however I suspect that'll take some trial and error and don't want to waste any. I want to go ahead and de carb It within the next couple hours so any tips would he greatly appreciated.
