Tomato paste is not the same as tomato puree. If you can’t find tomato paste, just cook some tomato puree on a low flame until it reduces into a thicker paste.
I used a dukkah mix inspired from Bon Appetit, consisting of toasted almonds, toasted sesame seeds, red chilli flakes, and toasted nori, and added some flaky sea salt in the end. But really, don’t get turned off by the nori; any dukkah tastes amazing with this!
