I had radiotherapy which ended in August 2012 and killed my taste buds followed by surgery to remove 2/3 of my tongue. As a result I had a PEG tube and used EnSure 2Cal. However I had to wean myself back onto real food. Forgetting the issues surrounding re-learning how to eat the upside was that my taste started to return. To start with I could only take 'gloppy' stuff like porridge, soup, custard, mousse and pâté.
However we invested in 3 pieces of kitchen equipment. Firstly we bought a slow cooker. The way it cooks makes everything soft so eating was easier. However, before I got to that stage we bought a Vitamix (https://www.vitamix.co.uk/). It makes smoothies, soups, purées but more importantly one can put in slow cooked casseroles and stews (or even curries, grilled steak or whatever takes your fancy) and it will pulp it to a manageable consistency. It's not just a blender because it is so much more powerful. We also bought a hand-held blender called 'Bamix' (http://www.bamix.com/).
These implements, fresh ingredients and a little imagination and inspiration plus a little help from Google really helped my return to a normal diet.
