A restaurant in London's Covent Garden is serving a new range of ice cream, made with breast milk.
The dessert, called Baby Gaga, is churned with donations from London mother Victoria Hiley, and served with a rusk and an optional shot of Calpol or Bonjela.
Mrs Hiley, 35, said if adults realised how tasty breast milk was more new mothers would be encouraged to breastfeed.
Each serving of Baby Gaga at Icecreamists costs £14.
Mrs Hiley's donation was expressed on site and pasteurised before being churned with Madagascan vanilla pods and lemon zest.
Icecreamists founder Matt O'Connor placed an advert appealing for breast milk donations and believes his new recipe will be a success.
"If it's good enough for our children, it's good enough for the rest of us," he said.
"Some people will hear about it and go yuck - but actually it's pure organic, free-range and totally natural."
He added that the ice cream was not certified organic.
Mrs Hiley, who gets £15 for every 10 ounces of milk she donates to the company, said it was a great "recession beater".
"What's the harm in using my assets for a bit of extra cash?" she added.
"I teach women how to get started on breastfeeding their babies. There's very little support for women and every little helps."
Mr O'Connor said 14 other women had come forward to offer their services. Health checks for the lactating women were the same used by hospitals to screen blood donors.
"No-one's done anything interesting with ice cream in the last hundred years," he added.
