Lime-Sea Salt Soda Syrup from The Artisan Soda Workshop

It wouldn’t be a stretch to say the SodaStream has changed my life.

A little carbonation is the only way I can happily get through my daily water quota, and in the little more than two years that the fizzy machine has sat on my kitchen counter, I’ve become a seltzer fiend, sucking down at least a liter a day.

But sometimes plain sparkling water—or even a squeeze of lemon—isn’t enough.

And while I could buy syrups that replicate the taste of Coca-Cola or Sprite for my soda-happy husband, I’m not digging the chemical additions and artificial flavors on their ingredient lists.

A splash of regular fruit juice or lemonade shake things up in a daily water routine, but often I want more.

Good thing my friend and cookbook author Andrea Lynn came up with 70 recipes for homemade soda syrups to stir into plain old seltzer in her new book, The Artisan Soda Workshop.

It’s tough to call this a cookbook per se because the recipes are so inspired, yet so simple.

Real ingredients—prickly pear, rosemary, kiwi, cantaloupe, and lemongrass—take the soda options way beyond orange, cherry, and grape.

Natural sugars like agave and honey are prominently featured in a bunch of recipes, making this a sweet option for soda lovers who stopped eating cane sugar.

As Andrea says:

“The magic is in the creativity. Traditionally, there’s no anything like a hibiscus soda on the market. But why not? Make a syrup from it, then add to seltzer, and voila. It’s so much more versatile than I ever thought it could be.”

And there’s a recipe for whatever time constraints you’re faced with, whether you need an instant hit of flavor or are planning a special signature cocktail for next weekend’s dinner party.

Quick-simmered syrups like the autumnal honey, concord grape, and pear syrup come together in minutes.

Fruity infusions like the unusually refreshing lime-sea salt soda syrup steep while you sleep.

And—my personal favorite—tart and bracing vinegar-infused shrubs like persimmon-black pepper build flavor slowly.

Yes, the book also features homemade versions of classic soda brands like Fresca, Cherry Coke, and a quick faux fix for Dr. Pepper.

Even if you don’t own a home seltzer maker, you can most definitely mix the syrups you make from The Artisan Soda Workshop with canned or bottled sparkling water.

They’re most definitely as refreshing with San Pellegrino or Polar seltzer as they are with home-carbonated water.

Though if you kick that last can of seltzer at 10:00 pm after an impromptu homemade syrup cocktail hour, I’m not the one making a convenience store run to bring you some more—you’re on your own there.

In fact, if you’ve got a saucepan, a spatula, and a strainer, you’re in good shape to make nearly any recipe in the book. They’re that easy and that worthwhile.

Try out Andrea’s—dare I say it?—life-changing recipe for lime-sea salt soda syrup below.

This magical lime-sea salt soda syrup turns regular seltzer into a non-alcoholic margarita, making your afternoon pick-me-up even more of a happy hour.

  1. Oh my gosh! You had me at Prickly Pear! We became soda streamers a few years ago, and James has really gotten into making his own syrups. His current favorite is a ginger lime he concocted that is heavy on the ginger. It’s a bit spicy for my liking, but he adores it. I would love to win this for him!

  2. Anything lime! This sounds great; can’t wait to try it. Another one that I love, as long as it tastes real: PEACH!!

  3. i’ve been toying with buying a SodaStream…except I don’t like soda (just seltzer). Still worth it?

  4. Love love LOVE my Sodastream too! A sour cherry soda would be awesome, but I’d love to try to make something Dr. Pepper-ish, too. Mmmm…

  5. I thought I would leave a review of this soda because I didn’t see anyone else mention actually making it.

    I found the recipe to be a bit too dry. If you make this soda, you might want to add just a touch more sweetener to make it taste more like a soda and less like a salty beverage.
