Beyonce Knowles has shown a down-to-earth side as she revealed the catering details of her recent wedding to rap mogul Jay-Z.Quite apart from spending millions on lavish catering, the singer drafted her mother Tina and husband Jay-Zs grandmother into the kitchen to provide the food for their reception at the rappers New York home.Tina Knowles told Giant magazine We cooked all the food. I cooked all my Creole stuff and his grandmother cooked her oxtails.My favourite part was when we put all of this home cooking on that fancy china. It was special.Catering for a family event or wedding party can be a challenge but the installation of professional quality appliances can make the job a lot easier.A Franke tap such as a model from the Trispray range allows kitchen users access to a variable spray jet, which makes dealing with large quantities of ingredients or dirty crockery easier and less time-consuming for the busy caterer.
