Cut the cleaned tongue into desired size chunks. Place in the electric pressure cooker with approx. 500ml water and the chopped vegetables (onion, celery stalks and the carrot). Add all the other ingredients (herbs, salt, Paprika, coriander powder, chilli flakes, tomato purée, cayenne pepper, nutmeg, bay leaves, thyme). I wasn't joking when I said all ingredients ? you see, well, all apart from the potatoes.
