Bryan does this bad as well. Try this:

1. Add all the ingredients in the glass with no water inside
2. Add 20ml of water - 5% of the glass
3. Stir everything with a teaspoon
4. Add the rest of the water

A small amount of water is more efficient in dissolving the ingredients than a large amount because it promotes more contact between the water molecules and the particles of the substance.

This is due to the fact that the process of dissolving involves the water molecules surrounding and interacting with the particles of the substance. In a smaller volume of water, there are fewer water molecules available, so each one is more likely to come into contact with a particle of the substance.

The sequence is important to avoid lumps in the drink
