Gross or tasty? A London company is offering an unusual dessert — ice cream made with human breast milk.

Trendy London ice cream parlor The Icecreamists said its "Baby Gaga" ice cream sold out as soon as it launched Friday.

The company paid women who responded to an online ad to donate their breast milk. The milk — which the company said was screened in line with blood donor requirements — is then pasteurized and churned together with vanilla pods and lemon zest. The dish comes in a martini glass and sells for 14 pounds ($22.50) each.

Some may be repulsed by the idea but Matt O'Connor, who owns the company, told the BBC that the product is "organic, free-range and totally natural."

"It's good enough for our kids, good enough for our ice cream," he said.

There are no specific laws in Britain prohibiting businesses from selling human milk products, the Food Standards Agency said, although they must comply with general food safety laws to ensure the product is safe for consumption.

Victoria Hiley donated the first batches of milk, earning 15 pounds ($24) per every 10 ounces (283 grams), the BBC reported.

About a dozen other women have signed up to donate more, O'Connor said.
