I was at my local homebrew shop putting together a recipe which called for a certain amount of liquid extract. The guy who was helping me said that since it was an odd amount that i would be better off with one can of liquid, and then a bag of dried. I didn't really think about this till now, but do i have to do anything different with the powder extract? Should i just add it at the same time as the liquid? Also Im sure there is some sort of exchange rate when going from liquid to dried but i cant seem to find it in the books i have. Any help would be very appreciated.
