Not so much a clear cut food today, more a way of making a beverage.
Tea in a Lock & Lock tea bottle…
Start with a good pinch of tea leaves
Fill with water and replace the strainer and lid
Let sit a few minutes and ready to drink. The beauty of this system is you can keep this on your desk and drink from it either hot or as it cools down, then take the top off, add more hot water, and repeat more or less throughout the day.
