• Do not add whipped cream to the top of your shots if you’re not serving them right away. You’ll want to keep lids on your shots and top them right before serving.
• For some strange reason, I had to go through three grape jello boxes as it seemed to react differently than the other flavors. If you have an issue with it not setting up, add less liquid, starting with the alcohol. You can also place it in the freezer before placing the last layer on.
• You can use any vodka or alcohol you prefer, just don’t go over ¾ cup alcohol in each layer as it won’t solidify if you do.
• Don’t try and add a new layer until the layer below it is solid. If it’s runny at all, it will make the colors mix.
• You can keep these in the fridge for up to 5 days, with lids.
• You can use other means to get the liquid in the cups. However, I have not found anything that works as quickly or cleanly as the injector.
