There is no need for me to repeat the recipe here, the only thing I did differently was to melt the chocolate and butter in the microwave as I usually do. That worked fine, but note that you should use very short 15-30 sec intervals and stir to ensure you don’t overheat it.
The recipe was easy to follow, super fast and the result was really delicious. The only thing I would change next was to use a little less sugar when using commercial jam (at least my homemade jams have much less sugar than the one you buy), I found it a tad too sweet.
It would also be great if you either got seedless jam or took the time to melt the jam and press it through a mesh sieve to remove the seeds – they ended up sticking to my teeth a bit. That will increase the effort for this brownie quite a bit though!
