Unfortunately don't have the room to keep multiple amari in hand. But, having this with Cynar, and suspecting the result beforehand, I would recommend following this recipe closely, as far as using sweeter, fruitier brands. At the very least, do not use an extra bitter, robust amaro... flipped the amaro to Strega ratio and it was too heavy in the latter direction... evened them out third try and it was more palatable, if the least dynamic... Interesting meeting of flavors...

Good. I have a theory these improve as a factor of quantity consumed in succession. To be continued...
