Slice the tempeh into long narrow strips.
400 g tempeh
Take a wok or sauté pan and cover the bottom of it with around half a centimetre of oil. It shouldn’t completely cover the tempeh pieces. Heat on high and then pan fry the tempeh strips until they’re golden and crispy.

While the tempeh pan fries, add in the peanuts to toast them off too. Altogether this frying process should take 10-15 minutes. If there's not enough space in the pan, you can remove the tempe first, and then fry off the peanuts for a couple of minutes.
0.5 cup peanuts
Once golden and crispy, remove the tempeh from the pan and allow them to sit on a plate lined with paper towels, to let any excess oil drip off. Set aside.
Wipe the pan clean, or use as-is, and pop back onto a medium heat on the stove. Optionally add a splash of oil or use oil spray (we prefer oil spray for this step), then add in the garlic, shallots, chillies, ginger, lemongrass, curry leaves and kaffir lime leaves. Cook for 3-5 minutes until fragrant.
4 cloves garlic, 1 tablespoon ginger, 4 kaffir lime leaves, 3 red chillies, 1 stick lemongrass, 8 curry leaves, 3 shallots
Finally, add in the tempeh, peanuts, kecap manis, light soy sauce and sugar. Stir well. Make sure it is all heated through and that the tempeh is well coated with the sauce. Remove the lemongrass and serve.
3 tablespoon kecap manis, 2 tablespoon light soy sauce, 2 tablespoon brown sugar
