Thanks a lot for all of your answers. Strangely the taste has changed. Now things are acidic, except chocolate mousse. So every day i make sure there is some in the fridge. Martin says it tastes like it should. But the disappoiting thing is that after a few mouth fulls it becomes tasteless again. Apparently it is quite common. I heard a phone-in programme on French radio (I am half French, Half american and get very good radio reception for French radio), and it seemed to be a common complaint. There is a recipe book to re-introduce the pleasure of eating to radiotherapy and chemotherapy survivors. It was created by 10 chefs and cancer dieticians. I am slowly translating it, but once it is translated i will poste it. It is as much about the look of food as the taste.
