I'm in the process of creating a new drink and I humbly request your help. The general idea involves taking a peach schnapps drink and cooling it with ice cubes that contain even more peach schnapps extract inside. As the ice melts, more alcohol will be gradually released into the drink, creating an increasingly stronger drink as time goes by. Due to this alcholic effect, I'm thinking of calling it a "peach curveball."
The plan works out great on paper but I've been having some trouble determining the right kind of ice cube tray. I guess my first question here is about the value of stainless steel ice cube trays. Are stainless steel ice cube trays
(like this one) really worth it? People have mentioned the risk of chemical leaching from other trays, but it doesn't seem that big of an issue. Then again, my drink relies on people drinking all of the ice cubes, so this could be a problem. My other options are using a glass ice cube tray (risk of microshards in ice cube) or sticking with the traditional plastic ones.
Anyway, can someone please provide some insight into this problem? If you're familiar with ice cube trays, is there anything else I should know (like the speed of freezing)?
