Simple Raspberry Soda Inspired by Flour Bakery

If you’re from the Boston area, you’re probably very familiar with Chef Joanne Chang’s famous Flour Bakery. Known for its over-the-top sticky buns, freshly-made sandwiches, and assortment of super indulgent cupcakes, cookies, and tarts, Flour is most certainly one of the top five bakeries in town.

Over the years, I’ve sampled my share of Flour’s baked goods, but one of my favorite things to order is actually not a pastry at all – it’s their housemade raspberry soda. Part of it is the actual soda, and part of it is the memories I associate with it.

About a year after I graduated college, Aaron and I upgraded to a new apartment in the trendy South End. At the time, we were both working in Back Bay and wanted to be able to walk to work, and we also needed a pet-friendly place for the puggle puppy we’d be bringing home the following month. Our new place had a concierge, courtyard, a small gym, central air, and was mostly occupied by young professionals and BU Medical students – ideal for making new friends. It also had wall-to-wall carpet and ended up being on the cusp of some slightly seedy areas, but we’ll focus on the positives.

It was summer, we had just brought Honey home, I had been promoted at work, Aaron loved his job, and to top it all off, Flour Bakery was right across the street. Several nights a week, we’d find ourselves there, in search of a sweet treat after dinner. Aaron would order some ridiculously awesome dessert like a Belgian chocolate brownie or homemade Oreo cookie, I would order a large raspberry soda (and take bites of his dessert), and we’d sit outside with a four-pound Honey on one of our laps and talk about our days. It was perfect.

Years later, those raspberry sodas still take me back to that happy place. I’m not sure what’s in Flour’s recipe, but I imagine it’s really simple – a raspberry syrup made from fresh raspberries, sugar, and water – topped with bubbly seltzer water. I kept my version simple as well, adding in just a touch of lemon juice to give it some brightness, and keeping the sugar to a minimum so the natural sweetness of the raspberries really shines through.

It’s a pretty drink, and one you must order if you make the trip to Flour. For now though, this homemade version is an excellent option.

Simple Raspberry Soda
Cook time
Total time
Recipe type: Drink
Serves: approximately ½ C. Syrup
  • 1 C. Organic Raspberries
  • ¼ C. Water
  • 2 Tbs. Organic Sugar
  • ½ Tbs. Freshly-Squeezed Lemon Juice
  • Seltzer Water
  • Ice
  1. In a small saucepan over medium heat, combine the raspberries, water, sugar, and lemon juice.
  2. Cook, stirring every once in a while, until the sugar has dissolved and the raspberries begin to break down (about 3-4 minutes).
  3. Turn the heat down to low and allow the mixture to simmer for an additional 5 minutes.
  4. Remove the saucepan from the heat and let the mixture cool to room temperature.
  5. Strain the raspberries through a sieve and press gently with the back of a spoon to squeeze out the juices.
  6. Fill a glass with ice and pour 2-3 tablespoons of raspberry syrup, followed by about a cup of seltzer over top.
  7. Stir to combine and enjoy!
You can replace the sugar with whatever sweetener you like. I also tried it with a combination of coconut nectar and stevia and I was a fan, but I opted for granulated sugar for photography purposes because it creates a brighter pink raspberry syrup. You can store any leftover raspberry syrup in an airtight container in the refrigerator for up to 2 weeks.

    Very pretty indeed. I could drink a tall glass of that right about now as it is very hot outside.
    I have some fresh rhubarb a friend of mine picked for me from her garden in my fridge right now. I think you have inspired me to make a rhubarb version of this treat.

    How pretty! Plus, I enjoyed your post about the joyous simplicity of walking to work, having a puppy on your lap, and sipping a raspberry soda!

    OMG, I LOVE Flour! I am obsessed with their low-fat double chocolate muffin. Its way too good to be anything close to healthy but it makes you feel a little better. This looks fantastic, I’m going to have to try it out!!

      I received Flour’s cookbook as a gift a while back and let’s just say it may be better not to know how much butter and sugar is in most of their recipes. 😉

    My brother just moved to Boston and I’m planning a visit in a few weeks. This will definitely be on my list of places to visit. Thanks for the tip off!

      Yes, definitely seek out Flour! Also, Veggie Galaxy in Central Square Cambridge has awesome vegan desserts. Their vegan lemon meringue pie is incredible.

    Oh yum! I like raspberries but I’m thinking strawberries sound good too! Hmm I wonder how blueberry would taste…
    My sweet tooth says “oh yea” to living across the street to a bakery…my waistline on the other hand, sadly says “oh NO”!

      Strawberries or blueberries sound really good! And yes – living so close to an amazing bakery was very dangerous. Thankfully, I also had a gym in my building and joined another one down the street. :)
