1 part Bourbon
1/2 part simple syrup
1/2 part freshly squeezed lemon juice
I made a batch of simple syrup recently and added some finely grated lemon peel to the pot to give it an extra citrus flavor. Haven't stopped mixing it with everything yet. We were getting back to basics the night we made a whiskey sour with the syrup and freshly squeezed lemon juice and it tasted so good we wondered why we don't order these more often. Actually if we knew a bar person made his/her own simple syrup and squeezed their own fruit we probably would.
Vodka sour = short lemonade = perfect start to summer
Make it the same as above just replace the bourbon with vodka. Now go try it with gin, rum, tequila, moonshine, etc...
