The co-founder of ice cream maker Ben & Jerry’s says that its parent company Unilever blocked it from launching an ice cream flavour that expressed “solidarity with Palestine”.

Ben Cohen announced that he will independently create the new flavour as part of a personal series highlighting causes the company has been barred from addressing publicly.

Ben & Jerry’s is known for its activism on social issues and has consistently spoken out on political, environmental and humanitarian matters – including the Israel-Gaza conflict.

The BBC has contacted Unilever for comment.

Mr Cohen’s statement deepens the long-drawn dispute between the world-famous ice cream maker and Unilever, the British packaged goods giant which has owned Ben & Jerry’s since 2000.

The co-founders said Unilever and its ice cream arm Magnum, which is being spun off from its parent company, had unlawfully blocked their company from “honouring its social mission”.

Mr Cohen said in an Instagram video on Tuesday that he is creating a new watermelon-flavoured sorbet, calling for ideas for the product’s name and what ingredients should be added.

The watermelon has become a symbol for solidarity with Palestinians due to its colours, which are similar to those of the Palestinian flag – red, green, black and white.

The American entrepreneur said Ben & Jerry’s were prevented by Unilever from creating the dessert.

“I’m doing what they couldn’t,” Mr Cohen says from his set in a kitchen. “I’m making a watermelon-flavoured ice cream that calls for permanent peace in Palestine and calls for repairing the damage that was done there.”

In 2021, Ben & Jerry’s refused to sell its products in areas occupied by Israel. Its Israeli operation was sold by Unilever to a local licensee, allowing its ice cream to continue being sold in the occupied West Bank.

The dessert series will be developed under Ben’s Best, Mr Cohen’s activist ice cream brand, he said in a statement to the press. The flavour is being produced independently of Ben & Jerry’s, the statement said.

Ben’s Best was first setup in 2016 to support former US presidential candidate Bernie Sanders, with the flavour “Bernie’s Back”.

Mr Cohen said he will develop other ice cream flavours that speak to the issues Ben & Jerry’s was silenced from addressing publicly by Unilever.

In September, co-founder Jerry Greenfield stepped down from Ben & Jerry’s after decades at the company, citing concerns that its independence had been compromised following Unilever’s decision to curb its social activism.

At the time, Ben Cohen said that “Jerry has a really big heart and this conflict with Unilever was breaking it.”

“My heart leads me to continue to work inside the company to advocate for its independence so that it can actualise the social mission, the values that it was founded on and has maintained for over 40 years,” he told the BBC’s PM programme.
