It’s summer here in Oregon, which means barbecues, camping trips and river floats are on the agenda for the next few months. I always love showing up with a gallon jug of pre-mixed margaritas for the party, so I’ve decided to share my recipe with you, the loyal reader.

[Update: I just realized – three years later – that there was some confusion about the amounts specified due to my suggestions regarding how many bottles to purchase for the recipe. I hope it’s more clear now, but just in case… You will need to buy two fifths of tequila and measure out six cups (you should be left with about two ounces), and you’ll need to buy one fifth of triple sec and measure out 2½ cups (this should leave you with about an ounce). I hope this helps, and sorry for the three years of confusion.]

I usually make this recipe several gallons at a time and I serve them in one of these classic, durable, insulated coolers. What I’ll do is add a couple of gallon-size Ziploc bags full of ice right in the cooler and it’ll keep the whole thing nice and cold all day long. And as an added benefit, the Ziploc bags will keep the melting ice from diluting the Margaritas as they sit.

Hey, are you looking for a single-serving Margarita? Don’t need to make twenty of these damn things? Well here’s a really solid recipe that we use at all our bars, and that I use at home!

    Here in Hawai’i margaritas are popular and a lot of the women that I hang out with order a island style margarita called “Li Hing Mui” margarita. Li Hing Mui is a dried plum treat that originated in mainland China but is a big part of island life here in Hawaii as we put Li hing flavoring on everything and anything from gummy bears to popcorn. A popular thing that people in Hawaii do is put about a dozen dried plums in a bottle of tequila and let it marinate. I was wondering if you heard of a Li Hing Mui margarita before and how you would recommend making this with your recipe.

    Jeffrey, my boyfriend and I have made your gallon recipe twice for parties recently. Not only are they a huge hit with our guests, but they seem to have quite an, ahem, aphrodisiac affect! To all those interested in a little extra merry making this holiday season, try some gallon margis on for size. They last in the fridge and are a great compliment to mole, stir fry, green curry, cheese plates… Be forewarned, dirty dishes, strewn clothes, lights left on all night, forgetting to brush teeth, wildly drunk sex, passing out, may all occur upon consumption! 😉

  • Thanks for sharing, Bonnie. I’m glad I could, uh, help!

    I love the recipe and have been looking for a long time to find something like this. I have a party coming up this weekend and was wondering how can i make this recipe Frozen. Can it be as simple as to refrig the mix and put into a blender with ice?

  • Jason

    It would be exactly that simple. Have fun!

    Made for the Superbowl. Huge hit. Very very strong…but very very good. Thanks for the recipe!

  • Glad you liked it, Tony!

    The margaritas are strong, but that’s a good thing, right?

    You just made my day, even if it does make me sad to think of beautiful Los Angeles while it’s 40 degrees here in Oregon.

    I’ll toast you with a margarita in a few months, however!

    Jeffrey I think I am not in love with you! I stumbled on this site looking for Margarita recipes and you were the 2nd post. I have to say I love love love your website! I have book marked it and rated it awesome in STUMBLE IT so others find it as well. I will be using it for every party going forward!

    I cannot wait to make this recipe this weekend. My daughter just turned 10 months and it has been a while since I drank so this Saturday the girls are coming over and we are getting Mad! I plan on having Daddy take care of the kiddies well into the next day as it sounds as if these ritas pack a beautiful punch! Thanks for sharing and making a new mommy look forward to her freedom time!
