Rinse the pearl barley well under cold water and leave to drain.

Melt the butter and 2 tablespoons of the olive oil in a very large frying pan and cook the celery, shallot and garlic on a gentle heat for 5 minutes or until soft. Add the barley, thyme, paprika, bay leaf, lemon rind, chilli flakes, tomatoes, stock, passata and ½ a tablespoon of salt. Stir to combine. Bring the mixture to a boil, then reduce to a very gentle simmer and cook for 45 minutes, stirring frequently to make sure the risotto does not catch on the bottom of the pan. When ready, the barley should be tender and most of the liquid absorbed.

Meanwhile, toast the caraway seeds in a dry pan for a couple of minutes. Then lightly crush them so that some whole seeds remain. Add them to the feta with the remaining olive oil and gently mix to combine.

Once the risotto is ready, check the seasoning and then divide it between four shallow bowls. Top each with the marinated feta, including the oil, and a sprinkling of oregano leaves.
