Welcome to the forum Laurak, I have pm'd the recipe to you. Once you have made the tikka paste, the tikka masala is cooked on the stove top, not in the Thermomix. Not sure if anyone has tried it in the TMX or not.
If you are ever looking for a recipe, the best way to find it is to google it
eg 'chicken tikka forumthermomix', if nothing comes up, try' chicken tikka thermomix' and if anyone has the recipe on their blog, you will find it.
You can use the search bar on the forum on the Home Page but I find Mr Google is much better at finding things for us
How are you getting along with your machine, what have you made so far and where do you live? You will find all the support you need here, please do join in our conversations and post a review of any recipe you try from the forum.
