Old school but it works: suck on a piece of hard candy and you don’t feel like a furnace is drying you out on a hot day. I do this mostly because it keeps me from mouth breathing Bonus points for great tasting candy! (And not stealing stale candy from your grandma’s candy dish….)
Bali’s Best Latte Candy is a long favorite of mine, they also make a coffee and espresso flavors.
It can be sourced at Cost Plus World Markets for around $2 a bag. Hard, crunchy, full of coffee-goodness. Even better melted into your morning cup of joe as well!
