Yes, mashed potatoes can be stored in tiffins without excessive water release by ensuring they are properly prepared and cooled before storage, and by using an airtight tiffin container.
The key to storing mashed potatoes without them becoming watery lies in understanding why water is released in the first place. This often happens due to condensation and the breakdown of the potato starch structure. Here's a step-by-step guide to prevent this:
Proper Preparation: Start with the right type of potatoes. Russet or Yukon Gold potatoes are excellent choices because they are starchy and fluffy. Avoid waxy potatoes, as they tend to release more moisture.
Cook Thoroughly: Ensure the potatoes are cooked completely until they are very tender. This allows for easier mashing and a smoother consistency.
Dry the Potatoes: After boiling, drain the potatoes well and return them to the pot over low heat for a minute or two to evaporate any excess moisture. This step is crucial.
Use Warm Milk/Cream: When adding milk or cream, make sure it's warmed. Cold liquids can cause the potatoes to seize up and release water.
Avoid Overmixing: Overmixing can break down the starch and lead to a gummy texture and water release. Mix gently until just combined.
Cool Completely: Allow the mashed potatoes to cool completely before placing them in the tiffin. Warm food creates condensation inside the container.
Airtight Container: Use a high-quality, airtight tiffin container. This will minimize condensation and prevent the potatoes from drying out or absorbing odors from the refrigerator.
Add a small pat of butter on top of the mashed potatoes before sealing the tiffin. The butter creates a barrier that helps prevent the surface from drying out and reduces condensation.
