The lunch reception hosted by Queen Elizabeth for Prince William, Kate Middleton and approximately 650 guests will include canapés, the wedding cake and a chocolate biscuit cake, the palace announced.
About 10,000 canapés which took 21 chefs to prepare, feature all UK-based ingredients. They include roulade of goats cheese with caramelized walnuts, poached asparagus spears with hollandaise sauce for dipping, and miniature Yorkshire pudding with roast fillet of beef and horseradish mousse.
Pol Roger NV Brut Réserve Champagne will be served along with other drinks, both alcoholic and non-alcoholic.
Designed by Fiona Cairns, the eight tier wedding fruit cake is made up of 17 individual fruit cakes and cream and white icing. Decorations include 17 different varieties of 900 iced flowers and leaves.
Each of the 17 flowers and leaves have a meaning behind them, according to the Language of Flowers. Some include Sweet William, grant me one smile; Honeysuckle, the bond of love; and White Rose, the national symbol of England.
The chocolate biscuit cake, requested by Prince William, was made by Mcvitie's Cake Company. They used the royal family recipe that William loved growing up.
The official harpist to Prince Charles will play during the reception.
