These treats may look like cute and innocent little things, but they can pack quite a punch. It is easy to take their colorful and fun-loving demeanor for face value and do more shots than a burley Irishman could handle. This is exactly why, when using high-proof alcohol, it should be taken into account that they are much stronger than usual. You can reduce the amount of alcohol and just substitute that amount for more water or juice.
This way everybody is safe. Unless, of course, you are only making a small amount and would rather the couple shots your guests receive be a bit more potent.
