Applebees perfect margarita recipe is as follows:

1 oz cuervo 1800
3/4 oz grand marnier
3/4 oz cointreau

Pour in to mixing cup with ice to the top. fill to 1 inch below the top with sweetand sour mix shake thouroughly and take a martini glass rim with Kosher salt add 1 olive and i slice of lime put a strainer on the mixing cup and gently pour into martini glass.

That is pretty much the rercipe as I made it over the last three weeks
