I bought a package of Uncle Ben’s rice in such cooking bags (not sure how it is called in english). It says to boil it for 10 minutes in water. So, since I only have a steamer and I know it’s possible, I tried it out.
You put the rice black thing of the Braun MultiGourmet in place filled with just enough water to cover the bag. The steaming time is about 40 minutes (I did first 20minutes then again 20 to test it).
That is basically it! I didn’t found to much info about it on the net about this, so that’s why I’m logging this.
