Biber salçası is a Turkish paste made from concentrated cooked red peppers and salt. It comes in two varieties: acı (spicy) and tatlı (sweet). The hotter version adds a deep, umami heat to cumin-spiced lamb in this pasta recipe, which in Turkey is known as markana. Traditionally, markana is served with garlicky yoghurt and a generous drizzle of chilli butter enlivened with pul biber and sumac. With flavours this loud, it’s best to use a large pasta shape such as paccheri, because its cavernous middles can hold satisfying morsels of the filling.
