How to Make Boba (Tapioca Pearls)

Tapioca boba is the foundation of our milk tea drinks and the topping customers expect when they order. Getting it right matters -- undercooked boba is hard and chalky, overcooked boba is mushy and falls apart. This guide covers the full process from dry pearls to ready-to-serve.

What You Need

Item	Details
Dry tapioca pearls	Black tapioca pearls from storage
Large pot	Filled with water (10:1 water to pearl ratio)
Brown sugar	For the soaking syrup
Slotted spoon	For stirring and testing
Timer	Use your phone or the kitchen timer
Rice cooker or warming pot	For holding temperature

Step-by-Step: Cooking Boba

Step 1: Boil the Water

Bring a large pot of water to a rolling boil. You need a lot of water -- at least 10 cups of water per 1 cup of dry pearls. The pearls need room to move around freely or they will stick together.

Step 2: Add the Pearls

Pour the dry pearls into the boiling water. Stir immediately for the first 30 seconds to prevent them from sticking to the bottom of the pot.

Step 3: Cook for 25-30 Minutes

• Keep the water at a medium-high boil the entire time
• Stir every 5 minutes to prevent clumping
• After 20 minutes, test a pearl -- bite into it. It should be soft and chewy all the way through with no hard white center
• If there is still a white center, keep cooking
• Total cook time is usually 25-30 minutes depending on pearl size

Do Not Undercook

The most common mistake is pulling boba too early. A hard white center means they need more time. It is better to cook 2-3 minutes too long than to serve undercooked boba. Customers will notice immediately.

Step 4: Rest for 20 Minutes

Turn off the heat and cover the pot. Let the pearls sit in the hot water for 20 minutes. This resting step allows the heat to fully penetrate the center of each pearl, finishing the cooking process gently.

Step 5: Drain and Rinse

Drain the pearls in a strainer and rinse briefly under cold water. This stops the cooking and washes off excess starch.

Step 6: Brown Sugar Soak

Transfer the drained pearls to a container and add brown sugar syrup:

1. In a saucepan, combine 1 cup brown sugar with 1/2 cup water
2. Heat over medium until the sugar is fully dissolved
3. Pour the warm syrup over the cooked pearls
4. Stir gently to coat every pearl
5. Let them soak for at least 15-20 minutes before serving

The brown sugar soak gives the boba its signature sweetness and glossy appearance. Without it, boba tastes bland and looks dull.

Batch Sizing

A standard batch is 2 cups of dry pearls, which yields roughly enough for 20-25 drinks depending on portion size. On busy days (Fridays, 4th Fridays, event nights), prepare a double batch before the rush.

Holding and Storage

Rule	Details
Holding temperature	Keep in the rice cooker or warming pot on the warm setting
Stir frequency	Stir every 30 minutes to prevent sticking
Maximum hold time	4 hours from the end of cooking
After 4 hours	Discard. Do not serve old boba. The texture degrades and becomes gummy
Refrigeration	Do not refrigerate cooked boba. Cold makes them rock hard

4-Hour Rule

Cooked boba must be discarded after 4 hours. Write the cook time on a piece of tape on the container so everyone on shift knows when the batch expires. There are no exceptions to this rule -- old boba ruins the drink.

Portions Per Cup

Cup Size	Boba Amount
Regular (16 oz)	2 tablespoons (~1 oz)
Large (24 oz)	3 tablespoons (~1.5 oz)

Use the boba ladle to scoop -- one full ladle scoop is approximately the right portion for a regular cup.

Common Mistakes

Mistake	What Happens	How to Fix
Not enough water	Pearls stick together in a clump	Always use at least 10:1 water to pearls
Adding pearls before full boil	Pearls dissolve on the outside, stay hard inside	Wait for a real rolling boil
Not stirring at the start	Pearls sink and stick to the pot bottom	Stir constantly for the first 30 seconds
Skipping the rest period	Centers stay undercooked despite long boil time	Always rest 20 minutes with the lid on
Cooking too short	Hard white centers	Test by biting a pearl at 20 minutes
Skipping brown sugar soak	Bland, dull-looking boba	Always soak in brown sugar syrup
Refrigerating cooked boba	Pearls turn rock-hard	Never refrigerate; keep warm or discard
Holding past 4 hours	Gummy, unpleasant texture	Track cook time and discard at 4 hours
Not stirring while holding	Pearls fuse into a brick	Stir every 30 minutes in the warmer

Prep Schedule

Plan your boba cooking around expected traffic:

Time	Action
Opening	Cook first batch, note the time on the container
4 hours after first batch	Discard remainder, cook fresh batch if needed
1 hour before expected rush	Start a fresh batch so it is ready in time
30 minutes before close	Stop cooking new batches
Closing	Discard any remaining boba

First Day?

If this is your first time making boba, ask a team lead to walk you through the first batch. Watching the process once makes the timing and texture much easier to judge. It is completely normal to need a few tries before you can tell when they are perfectly cooked just by looking at them.
