Have been looking for it everywhere and can't find it. Have looked in Countdown and New World in Porirua....anyone have any ideas where i can source it?

Have you a deli close by? They usually stock harissa paste.

or from the free range cook book:

2 tsp coriander seeds
1 tsp cumin seeds
4 lcoves garlic
1-2 hot chillies
1 tsp flaky salt
1/4 cup oil
1 tsp cayenne pepper
1 cup tomato puree
2 tsp rosewater or a pinch of sugar

toss the cumin and coriander in a dry frypan until they jus start to pop, watching closely so you don't burn them. grind in a mortar and pestle.

chop garlic and chillies and grind into a paste with the salt.

return crushed seeds to the frypan, add oil, chilli and garlic paste, and cayenne pepper. sizzle for a few seconds, then add the tomato puree. simmer over high heat for a few mins until mixture thickens. remove from heat and stir in rosewater or sugar.

store in fridge covered with a film of oil - will keep for a few weeks.
