No worries Mark, you're right about most tins not having much aroma, so adding some late hop tea sounds like an excellent plan for the EKG top up. It is a pretty good tin this one and I've made a couple, one fairly plain vanilla- style, the other as a partial mash.
Remember that not all of the tin needs boiling with some extra hops, just some of the goop, say 3- 400g can be boiled with a 3- 4 litres of water with the hops in a 20 min boil, or if you're adding LME just use some of that. At the end, just tip all the goop and malt extract in and use the yummy boiling wort to rinse the tins out and then into the fermenter.
Ha! That reminds me, back when I did kit & bits brewing, I quite often made some mistake that that point, usually I had one full tin and just part of another (unhopped malt) to add the end of the mini- boil. Invariably I'd either just tip both in without realising or get the part and full ones mixed up, (often I'd warmed the tin in hot water and took the label off so it wasn't that easy to tell the difference). There were a few SNAFUs back then, I still make plenty of them now in fact, but the beers were still drinkable!
