Cairns has been commissioned to create a traditional multi-layered fruit cake with a floral design for the royal wedding next month, along with a second one made from rich tea biscuits.
Fiona Cairns Ltd began on Fiona's kitchen table 25 years ago, when Patel - now managing director of the company - spotted the potential of his wife's beautifully crafted handmade cakes. In 2001, Kishore joined the company full time and the business moved out of their garden and into a state-of-the-art bakery in Leicestershire.
Cairns said Middleton has given detailed plans for the cake, which will be the centrepiece of the Buckingham Palace wedding reception. Cairns, 56, was contacted by William's office in February and asked if she would make the couple's wedding cake. "It's multi-tiered, doesn't have colour - it's cream and white (icing) - and it's a traditional cake but also quite delicate and modern, all the tiers will have a different theme," she said.
The Prince has also requested his childhood favourite treat - a McVities chocolate biscuit cake.
The commission has been a process of discovery for Cairns, who has also been asked by Middleton to feature around 16 different blooms and foliage for their meaning - known as the 'language of flowers'.
The cake designer said Middleton made her feel relaxed when they met around six weeks ago at Clarence House to discuss ideas.
"She has guided us right from the beginning and has quite strong ideas. That makes it much easier than a bride who has absolutely no idea whatsoever, which has happened in the past," said Cairns, who has been trained as a graphic designer as well as a pastry chef.
"But she knew very much what she wanted and she brought us mood boards and told us what influences she would like us to use on the cake," she added.
