I added 30g being completely useless at converting between oz and grams and I'm not looking it up I'll leave you to convert, again this didnt overpower it and if anything could have got away with a little more.
I used whole cloves and cant say they were particularly noticeable the main flavour I get is nutmeg and cinamon.
So perhaps crushing might get them to release a bit more flavour.
It look a good recipe, nice and boot warming for those winter nights

Good luck
