The one with the excellent champagne punch recipe

goes something like this:

2 bottles of bubbly

2 liter of ginger ale

64 oz mango passion fruit juice or your favorite juice, fresh citrus if you like

citron vodka to taste (at least 1/2 of a fifth)

pour over ice

if you have a liquid dispenser just throw it in and let guests help themselves, it stays sparkly for days
