Final answer:
To thicken with tapioca, measure and whisk it into a slurry with part of the liquid, add to the rest, then gently boil and simmer while stirring until the desired consistency is reached.
Step-by-step explanation:
To thicken a liquid using tapioca, there's a specific procedure you should follow to ensure a smooth consistency without lumps. First, measure the appropriate amount of tapioca needed for the volume of liquid you're looking to thicken. A general rule of thumb is to use 1 to 2 tablespoons of tapioca for every cup of liquid. Next, whisk the tapioca into a small amount of the liquid taken from the main portion to create a slurry. This helps prevent clumping. Once the slurry is well-mixed and smooth, pour it back into the main pot of liquid that you wish to thicken. Then, bring the mixture to a gentle boil, and reduce the heat to allow it to simmer. Constant stirring is crucial at this stage to further prevent lumps. The liquid needs to simmer until it reaches the desired consistency and the tapioca is completely transparent, which indicates it's fully cooked. This usually takes about 10 to 15 minutes. Remember to taste your dish and adjust seasoning if necessary, as tapioca itself does not contribute any flavor. Once thickened to the desired level, remove the pot from heat and let it cool slightly; it will continue to thicken as it cools.
