I still have some koh fun flour from making snow moon cake last time, thanks to Yochana's blog, I found a nice recipe to make this, it is taste like mochi, soft and nice.
100 gm. Tapioca flour
100 gm. Koh fun
850 ml. water
200 gm. sugar
50 gm. gelatin powder
1/2 tsp. banana essence
2 Tbsp. corn oil few drops of pink colouring
For dusting: 50 gm. koh fun + 20 gm. icing sugar
(1) Combine koh fun, tapioca flour and water in a pot and stir till evenly blended. Then add in caster sugar and gelatin powder and keep stirring for about 5 mins.
(2) Cook mixture over low heat till thick. Remove from heat and add in banana essence and cooking oil.
(3) Divide batter into two portions. Leave one portion plain and the other portion pink colour.
(4) Pour the plain portion into a rectangular tray - 10" x 14" tray and spread thinly then pour the pink layer on top and the use a spatula to spread evenly. Leave to set and then roll up like a Swiss roll. Cling wrap tightly and leave it to set in the fridge till it's very well set and then slice into serving size. Dust it with the dusting mixture. Serve..
