Flavored syrups (Monin, Torani)
The fastest way to add flavor + Brix at the same time. 2:1 sugar syrups built for cocktails. We reach for these in 70% of recipes — they're how café drinks get their consistency.
- Monin Vanilla Syrup (750 ml)Workhorse for milkshakes, frappés and any dessert slush. Real-vanilla note, no artificial aftertaste.
- Monin Salted Caramel SyrupUsed in our salted caramel milkshake. Better than DIY because the salt is dialed for cold drinks.
- Torani Butterscotch SyrupBackbone of the butterbeer slush. Cheaper than Monin and a better butterscotch flavor.
- Monin GrenadineReal pomegranate, not just red dye. Drives the color + sweetness in the Sonic Cherry Limeade copycat.
Frozen lemonade & juice concentrates
The cheat code. A 12 oz can of Minute Maid frozen lemonade concentrate is already at perfect Brix — just add booze and water. Used in shandy, hard-lemonade, and whisky-honey recipes.
Fruit purées (Perfect Purée, Funkin)
Real fruit purées beat fresh blending — they're already strained, stabilised, and at consistent sugar levels so your slush behaves predictably batch to batch.
- Perfect Purée of Napa Valley — MangoUsed by every cocktail bar in the US. One frozen 30 oz tub = 8-10 batches of mango margarita.
- Funkin Strawberry Purée (1 L)UK bar standard, increasingly on Amazon US. The frosé and strawberry-daiquiri base we use.
- Perfect Purée — Passion FruitHard to find fresh. Drives the tropical recipes (passion fruit margarita, painkiller variants).
Sugar-free sweeteners (allulose, monk fruit)
Diet sodas don't slush without help. Allulose is the secret — it freezes almost identically to sucrose but with zero net carbs. The single most-asked-about ingredient in our AI assistant.
- RxSugar Allulose (Granular, 1 lb)Pure allulose, no fillers. Dissolves cold. Use 60-80 g per litre of diet soda.
- Wholesome Allulose LiquidEasier for cold drinks — no whisking required. Slightly more expensive per gram.
- Lakanto Monk Fruit + Allulose BlendBest for keto baking-style protein shakes. 1:1 sugar replacement that actually slushes.
Protein milkshake base
The Fairlife + birthday-cake-whey shake is the most-requested gym recipe. These are the exact products that work — high-protein milk with enough fat to slush, plus a whey that doesn't go chalky cold.
- Fairlife Core Power Vanilla (26 g protein)Pre-mixed, pre-sweetened. Pour it straight in for a fast protein milkshake.
- Ghost Whey — Cereal Milk / Birthday CakeMixes smooth in cold milk. The flavor profiles are built for shakes, not training.
- Jell-O Sugar-Free Vanilla Pudding MixThe viral TikTok trick — thickens protein shakes without adding sugar. 2 tbsp per batch.
