This recipe makes about 2.5 gallons of medium-strength margaritas. That’s enough for 12-20 people, depending on how heavy they drink on average and how long the party is. It is also ideal for a 5-gallon water cooler that has a pouring spout.
3.5L Margarita mix (Mr./Mrs. T brand is a good one)
1.75L Tequila (a variety with 100% blue agave if you want better quality)
0.5L Triple Sec (Cointreau or Gran Marnier are much better substitutes if you want to spend the money)
3/4 qt Orange juice (mango juice or an orange-mango mix are interesting substitutes)
qty 3 Limes
1/2 bag Ice
Directions: The hard part is getting the proper mix of ingredients. Mixing can be done in any order. And, of course, the limes need to be squeezed. Finally, since the ice is going to eventually melt, you can hold back 10% of the alcohol and orange juice, adding them after half of the ice has melted. By the way, the orange juice is the secret ingredient in this recipe.
