I've seen other threads and opinions vary between 4 ounces being plenty and 1 lb not being enough. Could be dependent on freshness or people's taste buds, or recipes, I don't know. I've only tried it so far in an apple cider and I haven't taste it yet.
jaquiss2005, the malt itself is a little less than $2 per lb (454g). It appears that the best shipping option is USPS Priority International Flat Rate box, with a small box being $24 and medium box being $60. I think I can stuff 1 lb in a small box and 2 lb in a medium box but I'd have to check that. There could also be duty and VAT fees in the UK but according to one website, these don't apply to food items of only a few dollar value. If you could confirm that would be great. Not sure the best way for you to pay. Perhaps you can login at the USPS website, https://cns.usps.com/go
, create a label (using your credit card) and email it to me. I'll look into it more and get back to you with a personal message or you can message me.
If anyone has better ideas for shipping/payment, let us know.
