Java Ice cream application

Customer Statement: My hobby is making a home-made ice-cream. I am preparing a book about ice-cream making. As a part of my work, I collect recipes from many sources, books, web, magazines. I also have a lot of material about various ingredients, mixtures, kitchen utensils, etc. As a result, I have a collection of books, magazine and newspaper clips, web bookmarks, written notes, etc. I would like to replace that collection with a small program that will allow me to manage my recipes. I would like a simple and easy to use user interface. I would like to play with a prototype during the development.
