A dirty soda is a fountain soda with flavored syrup and a splash of cream poured over soft ice. That is the whole idea, and it is roughly fifteen years old.
The format started in Utah — Swig opened in 2010 and built a chain on it — spread through the Mountain West, then went national when it turned up on reality television and TikTok. Mountain Dew, McDonald’s, Dunkin’ and Slice now all sell packaged versions.
In Somerville, New Jersey, there is one place making them by hand, and it is not a soda shop. It is a bakery.
About This Article
This article is produced by Garden State Circle and is part of our local guide to ice cream serving Somerville, New Jersey. Businesses are named here because of what they publish or what they told us directly, and every detail was verified against the business’s own website or on the record with the business. No business can pay to be included in this article, to be described more favourably, or to change what it says.
Garden State Circle is supported by the businesses that participate in it. Participation pays for our ongoing work: keeping a business’s entry accurate, re-checking its record, and publishing a page of its own details that the business maintains. There is no paid placement in this article. Participation does not buy a place here, a position here, or anything the comparison table says. Ingredients, preparation and allergen handling change, and we record what each business publishes rather than inspecting kitchens. If you have a food allergy, confirm directly with the business before you order. Hours, menus and alcohol policy change often. Every detail here was verified on the date shown above.

How they got to West Main Street
Blue Sheep Bake Shop, 84 West Main Street, added dirty sodas this summer. The shop’s owner did not go looking for the trend. Her sister found it on TV.
“She’s like, how come you’re not doing these dirty sodas? And I was like, what are you talking about?” the owner said. Her sister explained. She was unconvinced. “It sounds a little sweet — not my thing.”
Her daughter pushed. They tried one.
“I’m like, oh my God, this is actually pretty good,” she said. “I just thought adding syrup to soda was going to be overly sweet. But the cream that you add — it kind of dilutes it.”
That turned out to be the whole problem, and solving it is why the ones here taste different from the ones in a can.
The build
There are four steps and one piece of equipment most places don’t have.
1. Nugget ice. Blue Sheep bought a dedicated machine for it — the soft, chewable pellet ice you’d recognize from a Sonic cup. The cup goes about three-quarters full.
2. Syrup onto the ice. The syrup is bumped directly onto the ice rather than into liquid. “The ice for whatever reason sort of absorbs the syrup,” the owner said.
3. Soda, almost to the top. About a quarter inch is left. Many of the fruit-forward builds start with Sprite — deliberately. “It tends to be less sweet, and it doesn’t have so much of a flavor, so the sodas really take on the combination of the syrups and the fruits.”
4. One ounce of sweet cream. House-made. This is the part that took research.
They make one size: 16 ounces.
The sweet cream is the actual work
Before launching, the owner and her daughter went out and drank other people’s dirty sodas — convenience stores, fast food, whatever was carrying them.
Something was wrong with all of them.
“The cream dissipated into the soda,” she said. “It didn’t stay streaky. I’m like, why is this not staying streaky?”
The look is part of the product — the cream is supposed to sit and marble down through the glass rather than vanish into it. So she went and figured out why it wasn’t.
“You can’t just add heavy cream to the soda, which I think is what a lot of these places were doing,” she said.
What Blue Sheep pours is a proprietary blend of different milks plus a thickening ingredient she won’t name, developed specifically so it holds.
“It maintains the creaminess of the soda,” she said. “It almost turns into — I don’t want to say a milkshake — but the creamy part is really the draw.”
That is the difference between a soda with cream in it and a dirty soda, and it is the reason a bakery is better positioned to make one than a drive-through.
What to order
If you’ve never had one: the Dirty Shirley. It’s a Shirley Temple with cream, and it’s the owner’s own pick — “as a kid, every time we’d go out to dinner with my parents, that’s what we’d always get.” Familiar enough that you know what you’re getting into.
The one that actually sells: Dirty Dr Pepper OG — Dr Pepper and coconut. It carries “OG” because it’s the original build from out west, where the whole category started. She is straightforward that it isn’t her favorite and equally straightforward that it outsells nearly everything.
Her other pick: Butterbeer, on a cream soda base. Harry Potter, and she describes herself as “a cream soda chick.”
Pretty Pink Paradise: Sprite, strawberry and coconut under the sweet cream. Tropical, and built to photograph — “it comes out really pretty looking.”
Guava Girl: the tropical end of the menu — guava and strawberry over Sprite.
The summer lineup leans where you’d expect — coconut, strawberry, guava.
All twelve, and what is in them
Blue Sheep publishes twelve signature dirty sodas. Every one of them finishes with the same house sweet cream; what changes is the soda underneath and the syrups that go onto the ice.
Nine of the twelve are built on Sprite. That is the choice the owner described above, and the table is what it looks like across a whole menu — the other three use cream soda, Dr Pepper and Cherry Coke, and those three are the ones named after the soda rather than the fruit.
| Drink | Soda base | Flavors added |
|---|---|---|
| Blackberry Sangria Sparkle | Sprite | Blackberry sangria |
| Blue Coco Crush | Sprite | Blue raspberry, coconut |
| Butterbeer | Cream soda | Butterscotch, vanilla, salted caramel |
| Cherry Vanilla Crush | Cherry Coke | Vanilla |
| Dirty Dr Pepper OG | Dr Pepper | Coconut, vanilla |
| Dirty Shirley | Sprite | Grenadine, vanilla |
| Guava Girl | Sprite | Guava, strawberry |
| Palm Beach Breeze | Sprite | Pineapple, coconut |
| Passion Dragon Dazzle | Sprite | Dragon fruit, passion fruit |
| Pretty Pink Paradise | Sprite | Strawberry, coconut |
| Raspberry Cream Dream | Sprite | Raspberry, vanilla |
| Strawberry Cream Crush | Sprite | Strawberry |
Any of the twelve can be modified three ways: extra sweet cream, cold foam, or an extra flavor shot.
Six soda bases are available across the menu — Dr Pepper, Coca-Cola, Sprite, cream soda, ginger ale and Cherry Coke.
Menu as published by Blue Sheep Bake Shop, captured September 1, 2026. The summer lineup is expected to change around September 15.
The names are the one thing they don’t do literally
Everything else in the case is named exactly what it is. A strawberry and champagne cupcake is champagne cake with strawberry frosting. That’s the house convention, and the sodas are the single exception.
“I thought these were super fun and they look really pretty, and I wanted to have more fun names,” the owner said. “That’s the only product line on our menu where we don’t name exactly what it is.”
Credit is shared, with one contributor singled out: her teenage daughter, whom she describes as the household authority on any drink costing nine dollars.
Fall flavors are coming around September 15
The summer menu is not permanent. Syrups for fall are already ordered, with a target of September 15 for the changeover.
The plan: keep the top sellers and the originals, drop the four weakest summer flavors, add roughly four fall ones. Expect the obvious — cinnamon, pumpkin, apple.
She is not certain how that will go, and says so.
“The thought of fall flavors in soda, it might be a little weird,” she said. “But I didn’t think I was going to like these to begin with, so I might surprise myself.”
The practical details
Blue Sheep Bake Shop · 84 West Main Street, Somerville, NJ
Hours: Tuesday–Thursday until 8 PM · Friday–Saturday until 10 PM · Sunday 11 AM–6 PM · closed Mondays
Dirty sodas are made to order in one 16-ounce size.
The shop moved its retail location to West Main and brought its production kitchen back from Bound Brook, so baking, ice cream and drinks now all happen in the same building. It also runs 20 rotating ice cream flavors, coffee and specialty lattes, and custom cakes.
Reported August 28, 2026, from an interview with the owner. Hours confirmed on that date. The full flavor list was checked against the shop’s published menu on September 1, 2026; the fall changeover is planned, not yet live.
