This recipe just doesn't work.
This recipe makes no sense. 150 degrees C translates into 300 degress F - I just cooked macaroni pudding for the first time, using this recipe, and it took 90 minutes - not 30 - to complete, and that was only after I pushed the temp up to 375 degrees F. And one tbsp of sugar is like no sugar at all - I'm guessing it needs at least 5-8 tbsp, maybe more. My kids were very disappointed. The person who posted this needs to edit it for accuracy.
