Notes
Biscuit cake: This is a tricky type of cake. It is easy to get something wrong. In fact, I have had huge trouble with it before. Sometimes it is not completely done in the middle. So make sure to do the toothpick trial exactly in the centre and don’t take the cake out too soon. If you take it out and put it back in too many times, it will collapse and become dry. Make sure the eggs are correctly beaten so you get the right texture. It should be fluffy on the inside.
Coffee: There is a distinct difference in the taste of instant coffee versus a good blend. This coffee’s main taste is coffee. So it is important to use a good coffee for the soak. Instant coffee is best for cream or the cake itself but I much prefer using coffee made with a coffee machine rather than instant coffee for the soak. It has a stronger more distinct taste to it.
