Britain's record-breaking heatwave produced 'particularly strong' onion harvest - leaving the vegetable with more potent tear-jerking defence mechanism than usual A record-breaking heatwave has made particularly strong tear-jerking onions When damaged onions release sulphuric compounds that make humans cry Experts believe current crop is drier and more likely to bring on waterworks

If chopping onions lately has left you looking like an emotional wreck, you can blame the weather.
The record-breaking heatwave that hit Britain in the summer, especially in late August and early September, has produced a particularly strong and tear-jerking harvest.
Onions have a defence mechanism that protects them from passing predators, such as mice or insects, who might otherwise have had a nibble.
When damaged, they release sulphuric compounds called synpropanethial-S-oxide to create nature’s version of tear gas.
