The steps to follow to cream butter and sugar by hand includes:/
Start by softening the butter.
Ensure that the butter is at room temperature, as the butter should yield to gentle pressure and not be melted or greasy.
Mash the butter.
Place the butter into a mixing bowl and then use the back of a wooden spoon or sturdy fork to mash it until it's smooth.
Next add in the sugar.
Pour the sugar into the bowl and mash the sugar into the butter to prevent it from flying out of the bowl.
Then smear and beat the mixture.
Use the back of a wooden spoon or a silicone spatula, vigorously to press and also smear the mixture for the creamed butter and sugar against the inside walls of the bowl.
You should also rotate the bowl as you do this as rotating the bowl helps trap air and also ensures that the sugar granules are also incorporated completely into the fat.
And continue this until the mixture transforms from a grainy, yellow paste into a pale, smooth and fluffy consistency.
This step usually takes around 10 minutes of continuous stirring.
