The move has made the 'clash of curries' a central theme to the campaign in the lead up to Thursday's referendum which will decide Britain's future in the 28-member European Union.
The Bangladesh Caterers Association (BCA) has sided with Patel to call for 'Brexit' to "save Britain's curry industry", arguing that free movement of people from Europe hampers the industry's ability to bring in trained chefs from the Indian sub-continent.
However, on the opposing end is the UK's Asian Catering Federation (ACF) which has been backing the campaign for Britain to remain in the EU, while continuing to lobby the government on staff shortages within the curry industry.

"The ACF recognises the contribution of EU members, especially those from Eastern Europe, who are prepared to undertake demanding work and anti-social hours associated with the hospitality industry," it said in a statement.
ACF president Yawar Khan has also written to British Prime Minister David Cameron to further discuss the problems faced by the curry industry but has meanwhile asked its members to vote to remain in the EU.

However, stricter immigration norms over the years have made it tougher for many of these restaurants to bring in qualified chefs from the subcontinent, leading to the closure of hundreds of curry houses in the past year.
"Curry has become a powerful symbol of our diverse and tolerant society, one that welcomes those who work hard, pay their taxes and contribute. That includes the generations of Indians, Pakistanis and Bangladeshis who have brought their wonderful cooking to Britain. But it also includes more recent waves of immigration from Eastern Europe who have also brought their own unique contributions to our country," says Keith Vaz, another Indian-origin MP who is campaigning for Britain to remain in the EU.
He said: "The heart of the problem is the current visa scheme which has set a salary threshold of 29,750 pounds for chefs, much higher than the average salary for cooks in curry houses. This makes it extremely difficult for the nation's curry restaurants to recruit chefs from abroad.
"This could easily be solved in a stroke of Priti Patel's pen by lowering the minimum salary requirement for chefs, something I have campaigned for along with MPs from all parties. But Priti has failed to address this vital issue and is now conveniently using the EU as a scapegoat."
"Ourcurryhouses are becoming the victims of the EU's uncontrolled immigration rules. By voting to leave the EU we can take back control of our immigration policies, save ourcurryhouses and join the rest of the world," she said.
Patel last month launched a "Save Our Curry Houses" campaign, blaming EU migration for the industry crisis.
With opinion polls showing a lead for the Vote Leave camp in the last few days, it would seem her end of the argument is resonating with at least some curry lovers.
