Home cooks in the US are missing key opportunities to save time and money in the kitchen, it has been suggested.According to Sara Hohn, chef and founder of KitchenetteCookware.com, Americans need educating on how to use their appliances, the right tools and better kitchen practise in order to truly reap the rewards that home cooking can bring.Ms Hohn said A lot of progress has been made in making the public aware of conserving energy throughout the home but the kitchen, with its many appliances and high energy usage, is often overlooked.The principle of green cooking has been developed by the chef to highlight better the need for better habits and more efficient use of hardware.Her tips include using an oven appropriate to the size of the heating or cooking task and staggering the placement of dishes in the oven to ensure good airflow for a more efficient use of heat.Another key way get greener in the kitchen is by using a food waste disposer such as a model from the In-Sink-Erator range, which grinds up organic matter and lessens the impact it has when entering the water system.
