Questions about cleaning, cake and taste

Hello fellow pipesmokers,
I bought my first pipe 3 days ago.

Since it is a new pipe, it still needs to build up cake. (It has got this black carbon? layer but I read that it still needs to build up cake)
Now I ask myself if I should clean the bowl after each smoke, just like I read in tutorials on pipe cleaning?

Doesn't it prevent the building of a good cake? Maybe don't clean the bowl for the fist 3 times?
Also I do not seem to get much taste out of my pipe/tobacco. If anything it tastes like ash.

The pipe is a Butz-Choquin big bowl

The tobacco I got with it was recommended by the guy at the tobacco shop. (I asked for a cheap one) It is a german aromatic.
Is this just because I am not experienced enough and as soon as I am getiing the hang of it the pipe will taste better? Or could it be the tobacco/pipe?
I apreciate you reading,
Jonas

Thank you!

I'll do that from now on.

This weekend I'll get to try some tobacco from my friends dad, hopefully his tastes better :P

I'm in my last year of school (19 y.o.), which is why I don't have much money and was looking for cheap tobacco, just to try it out but maybe something in the middle price range would have been better.

Haha it smells real good :P

@chris thanks I'll look into that

Thank you for those tips rothnh!
There is only one tobaccoshop where I live, they have a huge sortiment and I'm sure they can provide me with some samples.
It is awesome to get so much attention and suggestions on my first post haha, appreciate it very much!
