Y’all! It doesnt matter which piece you build the drink in. The easy way is to build the drink in the pint, and is ideal for drinks you aren’t straining, but doesn’t seal as well. For drinks you would shake quite a bit and potentially do tricks with, this is the correct way. Either way is correct if your counts, ice and techniques are correct
If you know your count it literally doesnt matter.building in the bigger tin is faster if you are shaking two shakers since the orientation is already correct and you can lift and shake
