My wife and I moved to our new house and we have an induction hob installed there.
We used our brikka(s) a lot and loved the results.
We bought a 4 cup musa for the time being but compared to the brikka it tasted like fermented horse urine.
So I decided to experiment:
Apparently the head from our 2 cup brikka fits the bottom of the 4 cup musa.
It worked! The results are fantastic.
I am going to purchase a 6 cups musa and see if it fits our 4 cup brikka.
The thread on the musa is a bit longer but it doesn't matter: just screw it hard until it locks to put pressure on the seal.
Use just the boiler tank from the musa and all the rest from the brikka as the coffee funnel filter of the musa doesn't have a rubber seal needed for the higher pressure.
Don't put too much water (fill the amount that matches the head. Not the tank)
