I know this sounds weird but it's the BEST "on the rocks" margarita, super easy, and ALWAYS a HUGE HIT at parties...
1 12 oz. can of frozen limeade
fill 12 oz can w/ 7 up & add
1 Corona beer
1/2 to full 12 oz. can of tequila (I use 1/2 can and they are QUITE POTENT )
Mix all in pitcher to melt limeade and serve over ice |
