Burnt toast, or any burnt food is only carcinogenic if you eat it regularly and substantially for several years.The odd slice of burnt toast, with the carbon scraped off, who wants it the carbon left on,anyway, will do no one any harm.
The damage is done by people eating burgers, sausages and such like which are burnt round the edges and the burnt area is full of concentrated flavour and absolutely delicious so gobbled up by the eater. possibly on a daily basis.
Giving my pots a bit of a boost after the winter


my toast was undercooked so I shoved it back in and left it too long, but not so long I couldn’t scrap the dark off with a knife.
