Beyond Singkong Goreng and Tape Singkong
Recently however, with the coronavirus pandemic, we have experienced shortages in wheat flour. Wheat is not produced of our tropical country but it is an essential ingredient in many of the food we enjoy, like bread, cake, pizza, pancake and many more. The flour shortage (along with plenty of stay home time) led us to researching Brazilian cuisine which is based a many of their bread and pastry dishes on tropical-plant flour like coconut, taro and cassava.
This gave us a new insight into how we can use the plants available in our farm and expand the possibilities of our kitchen.
Can cassava be used like flour?
Yes! And no. Cassava star cannot directly be used as substitute for flour, as it does not have gluten and does not stretch and rise like wheat flour.
That said cassava flour is moist and delicious in its own way, and it is suitable for gluten-intolerant individuals. Once you have learnt how to ferment it, you will be surprised at how versatile and delicious cassava starch is. In subsequent posts, we will be writing recipees on how to use your fermented cassava to amp up your meal, but first - in this post we will be teaching you how to extract and ferment cassava to get freshly fermented cassava starch and fermented cassava juice.
How to Ferment cassava
Wash and peel cassava
Cube cassava and blend it with water. As a general rule, you can use about 400-500ml of water per kilo of cassava.
Put your blendered cassava out in a large bowl, and cover. Leave it to ferment in room temperature for 24 hours.
4 - After 24 hours, the cassava broth will be bubbly and smell sour. But don’t panic, this is as it should be.
Use clean kitchen towel and sieve through the blendered cassava. Keep both the starch and the juice.
