When you're old enough to enjoy an adult potion, but still a kid at heart, might we suggest our 10 favorite candy and cocktail pairings (brewed in the test kitchens of Toads):  

• Twix + Old Fashioned (make it extra haunted with dry ice) - Dip if you dare
• Milk Duds + Buttered Bourbon Cocktail - Best paired with a cozy blanket and spooky flick
• Starburst + Jalapeño Margarita - Sweet, sour, spicy, superb
• Reese's Peanut Butter Anything + Sangria - Like a Halloween PB&J
• Sour Patch Kids + Mule of Your Desire - Try these 8 variations on a classic Moscow Mule
• Junior Mints + Rum Daquiri  - Bite, sip, and you've got a Mojito without the muddling
• Atomic Fireballs + Spiked Apple Cider - Stir with a broom (oops, cinnamon) stick
• Sour Lemon Mike & Ike's (or Lemon Heads) + Ginger Mint Gin & Tonic - The ginger does double duty, settling the stomach during the candy crash
• Milky Way + Negroni - For the hard-core chocolate fanatics, try a Chocolate Negroni
• Butterfinger + Painkiller - Rum, coconut, and nutmeg balance the peanut and buttery richness
