I would love a recipe and the technique. Those look AMAZING!

It seems to produce a better tasting shot. That also seemed to be a temp that outputs water at around 195 at the grouphead. I am not sure if it is normal to set the boiler temp in that range. I would love to hear what is normal if my temp isn't. I have also thought that my PID might not be perfectly calibrated.

I use a modified rancilio silvia. It has a PID with the boiler set at 216°F. I also have it moded for pre-infusion. I do a 10 second pre-infusion and a shot time of ~27 seconds. 20 grams in 40 grams out. There is an awesome local roaster, light house roasters, they have a variety of beans to choose from. I'm still learning and chasing that perfect shot.

That looks really tasty!
