Cook’s notes
- Shop-bought massaman paste usually contains chilli, so this one is made from scratch.
- Keep to the peanut butter amount: more fat can trigger reflux.
- Firm tofu works instead of tempeh.

Tempeh & Sweet Potato Massaman questions
What if I can't find fresh lemongrass?
Lemongrass paste from a jar works; use about a tablespoon in place of the stem and fry it with the spices. Check the label, as some pastes contain onion or garlic.
Can I use ordinary potato instead of sweet potato?
Yes, and potato is traditional in a massaman. Cut it to the same size; it may need a few extra minutes to become tender.
Why fry the tempeh separately?
It gets a golden crust and holds its shape. Added back with the green beans at the end, it stays firm rather than breaking up in the sauce.
