When I lived in Dublin in college my host-mom always made this when anyone had even a hint of a cough or tickle in their throat. The only difference is she made it with a shot of whiskey. And not that I'm opposed to that addition, but I'm pretty sure pediatricians frown on giving booze to toddlers, which is when I started making my lemon honey tea on a regular basis. Plus, why would you waste good whiskey on a kid, right? Anyways, this is my first line defense when anyone comes down with a sniffle, a slightly swollen throat or just needs a warm mug of pure love.
Juice one-half of a lemon. Add to mug. Drizzle in honey. Add hot water. Serve with a kiss, a hug and the promise of more whenever they want. (If serving this to young children or a sick husband, keep the shot of whiskey for yourself, because chances are you'll need it more than they will.)
P.S. While I don't gain anything from advertising them, Wedderspoon is an amazing little company that's importing the best Manuka honey into the States. -- it's all organic and sourced from New Zealand.
