MELBOURNE: One of Australia's most famous chefs said she was dismayed to learn killer cook Erin Patterson partially used her recipe when baking a poisonous beef Wellington that killed three people.

Patterson was found guilty this week of murdering her husband's parents and elderly aunt in 2023 by lacing their Saturday lunch with lethal death cap mushrooms.
