Hi Martin, Thanks for taking the time to visit my site and leave a comment. However, please do reread the recipe post and notes. You will see that I mention that the addition of flour is optional and to leave out if you prefer a thin consistency or if you are making gluten free version.The addition of flour is to my own preference as I like it a little thicker. The recipe notes also provide other options for thickening such as mixing with rice etc. I have tried to provide as much information as possible so that the reader can make this recipe as they would like it, including making to a thin consistency. As for flour clumping and adding an unwelcome taste.....yes this is the case if you add it directly and don't give it time to cook out. However, i suggest adding a bit of water and making into a paste before adding gradually and stirring until thickened (and therefore cooked out). Like all recipes everyone has their own slant and preference. I always add optional extras to my recipes in the hope that I will give people the opportunity to make the recipe in the way they prefer. AND I always state when these things are optional......as is the case here with the flour. I hope you do give the recipe a try and leave out the flour (as to your own taste). Debbie
