How to Make Sugar Syrup and Boba for Café Counters

Running a busy café counter means prepping key components—like sweetener syrups and chewy boba—fast, consistently, and to the right spec. Whether you're serving milk teas or flavored lattes, getting these fundamentals right saves time and keeps drinks on-brand.

To serve 1,500–2,000 RMB/day in syrup use, prep 300 ml units (10 oz); for boba, plan 200 g per 10 cups (40 g each). Both take under 20 minutes start to finish with clear steps.

How to Make Café-Grade Sugar Syrup

This simple syrup forms the base for sweetened drinks and flavor infusions. Most counters prepare it in 300 ml (10 oz) units—a daily prep volume suited for 1,500–2,000 RMB in drink sales. Adjust quantity based on current stock and expected counter throughput.

Ingredients & Tools

Use white or soft (caster) sugar. Equipment includes a gas or induction stove, a Japanese snow-style (snow) pan, a bar spoon, and a measuring cup.

Steps

• 1. Measure: Base unit is 300 ml syrup. Scale up/down based on usage.
• 2. Boil Base: In the pan, mix water and sugar at a 1:2 ratio. For 300 ml syrup, use 150 ml water and 300 g sugar. Bring to a rolling boil over high heat.
• 3. Add Sugar: Stir in soft sugar (preferably cane-derived) until fully dissolved. Continue stirring for 3 minutes, then reduce to low heat.
• 4. Simmer: Cook until surface bubbles become small and the syrup turns a light golden sheen; it should feel noticeably thick when lifted. Then turn off heat.
• 5. Cool: Pour syrup into a measuring cup and let cool at room temperature away from direct light.
• 6. Store: Transfer cooled syrup to a labeled bottle for service.

How to Cook Perfect Boba Pearls

Boba pearls need precise timing and heat control to develop their signature bounce and chew. This method yields enough for roughly 10 milk tea servings (40 g per cup).

Ingredients & Tools

Use cassava-based tapioca pearls. Equipment includes a gas or induction stove, a snow pan, a bar spoon, and a measuring cup.

Steps

• 1. Measure: Base unit is 200 g pearls—enough for around 10 cups. Adjust based on sales volume (minimum increment: 100 g).
• 2. Boil Water: Use a 5:1 to 7:1 water-to-pearl ratio. For 200 g, boil 1,000–1,400 ml water. Higher pearl amounts or stronger heat need more water.
• 3. Cook: Add measured pearls to boiling water, stir well, and cover. Cook on high for 3 minutes, then medium for 4 minutes, then low for 5 minutes. After turning off heat, let sit covered for 3 more minutes (total cook time: 15 minutes).
• 4. Check Doneness: Pearls should float, double in size, appear shiny black, and have a smooth exterior with a firm, chewy center.

How to Store Boba After Cooking

Proper cooling and storage prevent boba from oxidation and maintain texture for service.

Steps

• 1. Cool Quickly: Run hot pearls under tap water to bring temperature down fast.
• 2. Ice Bath: Transfer cooled pearls into a syrup mix with ice. Use a 2:1:1 ratio of ice/sugar syrup/pearls—for 200 g pearls, use 400 g ice and 200 g syrup.
• 3. Hold Time: Stored this way, boba remains fresh for up to 6 hours.
