To minimise waste, pour your sugar into your clean dry mould so you know exactly how much you need.

Then decant the sugar in the mould into a bowl and add a small amount of water to the sugar. You only need a small amount of water - just enough to moisten the sugar, you don't want to dissolve it! Your best bet it to start with a teaspoon of water and mix it into the sugar so that it has a sandy feel to it. If you need to add more water do so in very small quantities.

Put the moistened sugar into your mould - pressing down with your finger so that the sugar is tightly packed.

Cover and leave to dry for 24 hours.

Pop the sugar cubes out of your mould and keep in an air tight jar.

Now decide if you want one lump or two!
