This recipe was given to my grandparents by a spunky 90 year old (or should I say young) opera singer one day while he was digging in his garden. He valued his voice greatly and refused to take any "modern medications" that might numb his throat instead of heal it.
Recipe: 1 Lemon, Good Cold Pressed Olive Oil, Honey (optional). Go around the lemon - poking it with a fork and then put it in the oven (350') until juice bubbles out the holes. Cool. Squeeze the lemon and put the juice in a jar. Add an equal amount of olive oil. Add some honey if you like. SHAKE! Take a small spoonful now and again - like a lozenge.
