Step by step

Work the ingredients for the sponge base

To cut the sponge in two horizontally so that you get the perfect result, we recommend using a long knife with a serrated blade and, if possible, use an object like a thick strip of wood or a cutting board as a guide to keep the cut horizontal. As for the lemon zest, never grate the pith or white part which is bitter, but just the yellow peel which gives flavour and aroma. Furthermore, regarding the gelatine, dissolve it gently in a heat proof bowl over some simmering water - it must not be cooked. You won’t need to leave it very long to get the desired soft consistency.
