I think everyone already knows it is good to put some water in the shaker before the powder to avoid sticking. If you don't know that, well now you do.
I usually put around 100-150g of water, followed by the powder and top with rest of the water and a whisk ball.
All fine and dandy but now, instead of water, put equal amount of crushed ice first, followed by everything else. Boom, instant cold and refreshing Queal perfect for the hot summer days! Enjoy!
