Since the weather has been so nice recently we've been eating some lighter meals such as quiche. In the quiche I make you use natural yogurt and I tend to buy a big pot of it. After we've had the quiche comes problem with what to do with the rest of yogurt. It has recently been Zero Waste Week in the UK and I've read many blog posts with peoples' endeavours on reducing waste in general around the house. According to Love Food Hate Waste we throw away 7 million tonnes of food and drink each year in the UK. With this in mind I had a root around in my fridge and found a sad looking lemon that needed a proper purpose in life. Yogurt and lemon? It has the makings of a cake in just two ingredients. On the way home we picked some blackberries to put on the top. Along with autumnal raspberries they are a great seasonal fruit which are good for you and your brain as well.
One of the main points of Zero Waste Week is the need to reduce consumption in general. It's certainly something that has become fashionable in cooking as well. Much has been written recently about how to cut down on sugar in your diet. Since I do like my cake I've decided to lower the sugar content in this cake. It also has a reduced amount of the fat in it as well. To achieve the lightness I've separated the eggs and then whisked up the egg whites before folding in.
