To be fair even 5 mins makes a big difference. It isn't quite the same as proper steeping though. Not with vanilla custard anyway (I tried).
Yeh I had some of the joose liquids straight out of the envelope yesterday and they had a horrible chemical aftertaste to them, I did what I just said with the hot water etc. and left them with the top off overnight and definitely a lot better. I have not tried steeping for longer than 3 days so far but I found that doing the hot water etc. for a few hours is as effective or better than just leaving them with the top off for 3 days.
I think I am going to buy the stuff to build my own coils and DIY my own liquids so I can make it how I want and also once you have all that stuff the running costs per week are almost nothing. If the Ekowool is not best for the protank wicks then what material is best? What type of wool?
