While many poisoners throughout history have stirred their deadly potions and powders into drinks, some of the more culinarily inclined have crafted killer dishes instead. The nurturing image these poisoners often presented—with casseroles and cakes always at the ready—may have even helped distract from their murderous ways.

1. NANNIE DOSS’S APPLE AND PRUNE PIE

Nannie Doss (1905–1965) poisoned as many as 12 family members. She allegedly added poison to both prune cake and an apple-prune pie, soaking the fruit overnight in rat poison. Her reported recipe included sprinkling the top of the crust with sugar when it was fresh from the oven, which probably helped disguise the taste of the poison.

2. ANJETTE LYLES’S BANANA PUDDING

Anjette Donovan Lyles (1925–1977) owned and operated a thriving luncheonette in Macon, Georgia. She was known for simple Southern fare and desserts such as her banana pudding with vanilla wafers (which you can find a recipe for here alongside a selection of her other popular creations). She took frequent breaks from the restaurant to tend to two dying husbands, a mother-in-law, and a daughter, all of whom she killed by adding rat poison to their food—though it's not clear precisely which specific dishes she served them.

3. BLANCHE TAYLOR-MOORE’S PEANUT BUTTER MILKSHAKE

Blanche Taylor-Moore (1933-) dispatched of at least three people in a prolonged and agonizing fashion by repeatedly serving them arsenic-laced meals. She then hindered recovery by bringing digestive-friendly foodstuffs laced with poison (including banana pudding) to their hospital beds. Shakes made with vanilla ice cream, milk, and creamy peanut butter were the favorite of her second husband, the Reverend Dwight Moore, who survived despite reportedly having 100 times the normal levels of arsenic in his system.

4. LYDA SOUTHARD’S APPLE PIE

She sprinkled it with cinnamon, a dash of nutmeg too
And sugared it with arsenic, a tasty devil's brew.
That famous apple pie, which ne'er forgot will be,
And for Lyda Southard's apple pie, men lay them down to die.

Lyda Trueblood Southard (1892-1958) and her family are said to have moved from their home in Missouri around 1907 after seeing a photo of a man holding a cantaloupe-sized apple grown near the new town of Twin Falls, Idaho. She put these apples to use in pies ... along with arsenic from boiled flypaper, which she reportedly used to poison four husbands, one daughter, and a brother-in-law [PDF]. Although she proclaimed her innocence to the end, it's rumored that her body was hairless, revealing a prolonged exposure to arsenic.

5. LYDIA SHERMAN’S CLAM CHOWDER

Lydia Sherman (1824-1878) poisoned three husbands and eight children with milk, oatmeal, and New England clam chowder. The standard Civil War recipe involves salt pork, potatoes, shucked clams or quahogs, and plenty of milk and cream. In Lydia's case, it also involved arsenic, which helped earn her $20,000 worth of real estate and $10,000 in cash after one inconvenient husband died. She went the easier route with her next husband by simply adding arsenic to his bottle of brandy.

6. DEBORA GREEN'S HAM AND BEANS

When Debora Green's (1951-) marriage dissolved in the summer of 1995, her husband began suffering from mysterious bouts of nausea, vomiting, and diarrhea. Although he at first blamed the symptoms on a bug picked up during a recent vacation in Peru, investigators grew suspicious after a fire burned down the family home that fall, killing two of the couple's children. Police looking into the blaze soon discovered that Green had burned down her own home in a rage—and that she been poisoning her husband by putting castor beans in his chicken-salad sandwich and ham and beans. Castor oil is commonly used as a laxative, but when crushed, the beans produce the deadly toxin ricin.

7. LOCUSTA'S MUSHROOMS

The Roman emperor Claudius (10 BCE-54 CE) loved mushrooms, a fact that the notorious female poisoner Locusta allegedly used to help finish him off. Locusta was acting on the orders of Agrippina the Younger, Claudius's fourth wife, who wanted to clear the path so that her son Nero (from a previous marriage) could ascend to the throne. Historians debate whether the assassination ever really happened, but some report that Locusta added the juice from death cap mushrooms (Amanita phalloides, known as "the destroying angel") to a dish of Claudius's preferred fungi, Amanita caesarea. The details after that vary—a poisoned feather stuck down Claudius's throat or a poison enema may have also been involved—but either way, the death would have been slow and painful.

8. CAROLINE GRILLS’S TEA CAKES

Caroline Grills (1888–1960) was a prolific baker known for bringing home-baked cakes and cookies to tea with relatives. Unfortunately, Grills was lacing her goodies and tea with thallium, a popular rat poison, and may have killed as many as four family members doing so. The symptoms of thallium poisoning often involve fever, delirium, convulsions, and progressive blindness, followed by death.

Still, Grills's sweets were so delicious that even when she was under suspicion of murder, it didn't stop people from consuming them: One relative given some candied ginger couldn't resist trying it and was rewarded with pains in his neck and chest and numbed toes. Grills was eventually arrested and charged with four murders and one attempted murder, but only convicted on one count. Her case was part of a string of thallium poisonings in post-war Australia, with dozens of cases, several high-profile trials, and 10 deaths.
