July Cocktail of the month - French 75

Yes, July in September. It makes sense somewhere. And this, in honor
of Cheek and Mary's nuptial city. To make these at home:
Shake with ice:
1 shot (oz) lemon juice
2 shots cognac
1 tsp or so of sugar
Strain into champagne glass and top with approx 4 oz of dry champagne
(should be about half champagne and half lemon-cognac-water-from-ice
mixture)
Enjoy!

Oh, and I like to call these a Soixante Quinze instead of French 75.  You can figure it out.
