Ooops. Sorry Dmtaylor, should have checked back earlier.
Ended up with 10 lbs of 2-row, 2 lbs of jaggery, 1 tbsp of black patent at sparge.
Mashed at 1.049 for 1 hour. Added 1 oz of Centennial at 60, 1 oz of Amarillo at 10 and 1 oz at flameout.
Didn't help that my neighbour came by and we kicked my keg of Centennial APA that was awesome. So, this will probably be a higher alcohol APA with Kolsch yeast instead of WLP001 like last time. Not the best planning and forethought but hey, can't do everything perfect. I am sure the jaggery will only end up as more alcohol and the flavour will be lost but hey, there's always next time.
Final result is 20 L of 1.076 OG wort.
