Place in a pot and cover with water.Boil for 10–15 minutes, depending on size, until very soft and fully cooked through.Cassava needs to be fully cooked to be safe to eat.Drain well.
Transfer to a bowl. Mash while still warm until mostly smooth with some texture.
Add salt and brown sugar. Mash to combine.
Add condensed milk and melted butter. Mash until well combined.Taste and adjust if needed.
Shape into portions or press into a greased dish and slice.You can also use an ice cream scoop, like I did.
Top with softened butter, grated coconut, cheese, or all three.
Notes
Cassava: Use fresh or frozen (thawed). Do not use grated cassava — it can turn out too soft.
Condensed milk: Adjust to taste.
Light brown sugar: Optional. Adjust to taste.
Butter: Margarine works as a substitute.
Toppings: Butter, grated coconut, cheese, or any combination.
Cooking Tips
