Typo in the ingredients list!

While you wait for the recipe writer to respond, may I suggest you simply start with 2 teaspoons of curry powder? That would make the most sense, given the amounts of other ingredients. As with most spices though, the exact amounts you prefer to use are up to individual interpretation, so you can add to or detract according to your own taste preferences. If you start with the lesser amount, and find it lacking, you can always add more. On the other hand, if you opted to use a large amount and find it overtakes the rest - you are just stuck.
