First use of the mousse ring I bought from Berlin.  The cake look more like a regular cake than mousse cake.  It taste a bit too sweet and the mousse was not smooth enough.  I have to search for a better recipe.  Maybe I should look for german cheesecake recipe (which has a fairly airy and light texture) to try out this mousse ring.  BTW, can you believe this mousse ring only only 4.99 Euro (included tax – VAT) and it is made in Germany too.   I bought it from Berlin.
