After, otherwise it’s sickly sweet IMO
Edit: 1:1 ratio. That goes for honey syrup as well just in case you want to make a Bee’s Knees or a variation thereof IMO
Never have cut the agave with water, since it will mix a lot easier than honey (which I have cut, bee's knees and bitter bee are delish).
I made some margs as you suggested and they were great! Excellent recipe my man.
