2 2/3 cup sugar
2/3 cup white corn syrup
2 egg whites
2/3 cup water
2 tsp vanilla (or other flavorings if you like)
Cook sugar, corn syrup and water to 260* or hard ball. Beat into stiffly beaten egg whites. Add vanilla and nuts and drop from spoon to waxed paper. (if you try to drop hot liquid it won't work so my trick is to fill the sink 1 inch with cool water and place the bowl in there while still mixing. Make sure you only keep it in there until the color changes and starts to stiffen up. If you leave in there to long the whole bowl will stiffen and you won't be able to drop onto waxed paper.)
Definitely play with the recipe, it's worth it once you've figured it out.
