Are the curry pastes vegetarian?
Not all — several traditional pastes contain shrimp paste or fish sauce. Check the individual pack, as vegetarian versions are labelled.
How hot are the curry pastes?
Green is generally hottest, red medium, massaman mildest. You control the final heat by how much paste you use.
What can I use instead of fish sauce?
For a vegetarian dish, light soy sauce with a little lime works as an approximation, though the flavour is different.
Do lime leaves need to be fresh?
Dried work perfectly well in a simmered curry. Fresh are better where the leaf is finely sliced and eaten.
How should I store opened coconut milk?
In a covered container in the fridge, used within a couple of days. Not in the opened tin.
