Nice stiff peaks. This photo was taken holding the bowl upside down in the air, and the egg whites didn't fall out. We had to swap out extract for pandan leaves, as we couldn't find pandan leaves during lockdown here in London. Also, we added lots of green food colouring to the finished batter, but due to the amount of dark egg yolks used in the recipe, the green food colour didn't show up. The cake is still very yellow. It tasted great, but will try the recipe again to see if it will rise higher next time. Our cake tin is 10in x 4in (25.4cm x 10cm). Do not use a non-stick pan. The batter needs to cling to the edges of the pan as it rises.
