That's a good suggestion, and I'll give that a try. Having thought about it a little more deeply yesterday, it seems clear that the contents of the LME cans are already pasteurized. So I guess my only concerns are ensuring I sanitize everything properly (454k30's tip about the can opener and the outside of the cans was a good one!).
On that note, would it be wise to boil the water I use to top the fermenter up with? The kit instructions suggest to simply pour the LME in with a few litres of boiling water, then top up with cold water from the tap. That seems like a pretty good vector for contamination.
Perhaps I'm overthinking things, but I'd like to get a good brew for the first time :-)
