THE St Albans restaurant scene has acquired yet another new level with the arrival of Chez Mumtaj, where managing director and executive chef Chad Rahman is pursuing his dream of introducing to the city what he calls modern Asian fine dining with French overtones. Winner of a number of high profile chef of the year awards for his work at his original St Albans restaurant, Mumtaj, a city fixture for 25 years, Chad is branching out. The setting for Chez Mumtaj is lavish, a large double-fronted former furniture store which has been transformed into a luxurious 100-cover restaurant with additional facilities for private dining. Opened at Easter, it is already turning people away on Saturday nights. The food, seeming familiar at first glance, is determinedly different, as Chad's recipe demonstrates.Risotto of Devon crab with tandoored king prawns, basil and truffle foam and smoked aubergine caviar (serves 6)Risotto base:1 litre shellfish stock 50ml olive oil2 shallots and 2 baby leeks, finely chopped1 clove garlic 1 cup Arborio rice 4tbsp white wine 2 sprigs fresh thymeBring the shellfish stock to a simmer in a saucepan. Heat olive oil in deep heavy saucepan over medium heat. Add shallots, chopped garlic and baby leeks, sweat for 3 mins without letting them brown, add rice and sweat for a further 2 mins. Pour in white wine and simmer until it has reduced to a glaze. Add the hot shellfish stock in batches of 50ml-75ml at a time, bringing to boil each time and allowing to evaporate while stirring continuously. Each stage should take about 3mins. Repeat until rice is nearly cooked but not chalky - about 15mins from first addition of stock. Retain excess stock. Remove risotto from pan, ensuring rice is reasonably dry, spread over a tray and set aside to cool.
