Squeeze half a lime into the shaker, then half a lemon.
Add the ginger and jalapeno slice.
Shake until the outside of the shaker is almost too cold to touch.
Strain into a glass filled with ice and top off with the ginger ale. Adjust the amount of ginger ale to your own tastes
Garnish with lime, lemon, and jalapeno slices.
For Punch
Click on the serving size and slide the slider up to the number of servings you need. The ingredients amounts will adjust, too.
Add all of the ingredients except the ginger ale to a mixing bowl.
Keep in mind that the jalapeno will become hotter the longer the punch sits - you may want to add that with the ginger ale.
When you're ready to serve add ginger ale. Serve over ice.
Notes
It's really fun to make the cocktails in a pint jar with a twist on lid and put the jars in a container of ice. They'll be cold when your guests arrive and everyone can grab their own. Don't add ice if you do it this way - it will dilute the drink.
