My brisket doesn't have a lot of flavor on the inside. The outside is full of flavor but when getting to the inside it doesn't have much flavor to wow my guests. How do I get more flavor to the interior?  I'm cooking it in the oven, by the way. BBQ is not my thing. 
The closest thing you are likely to find is a product called Wondra flour.  Like idealmjöl, it is a pre-gelated wheat flour, but unlike idealmjöl it also includes some malted barley flour.  One post on this forum implies they may be interchangeable.
