Homemade Cranberry Lime Infused Vodka -- tried and it was a HUGE hit that I will definitely be making again! I made sure to make homemade tags that said to drink straight or try on the rocks with club or lemon-lime soda.
Infused Vodkas: If you really want to boost someone's holiday spirits, steep vodka with tangy hibiscus, refreshing cucumber and lime, or zesty horseradish. Decant your handiwork in beautiful bottles that cost about a buck apiece.
Infuse alcohol with various flavors. Steep them for three days in a sealed jar, strain them into individual bottles, make some sparkly labels (with a glue pen and loose glitter), and add a jingle ball for a festive finishing touch.
