Thank you for being so specific in your recipe. There are a lot of differences in alcohol and liqueurs and it's nice to see why you choose a specific brand or type.

By the way, not all Sonic's sell the ice by the bag. I tried recently to get some and the local Sonic didn't sell it by the bag. So call first. I ended up going to a restaurant I frequent and they just gave me a few big ziploc bags. Enough for what I needed.
