Roast caraway seeds in a pan without fat. Pour beans into a sieve and rinse. Bring stock and beans to the boil. Wash coriander, shake dry and, except for something to garnish, pluck leaves from the stems and cut into fine strips.
Peel and coarsely chop the garlic. Add 2 tablespoons of oil, lemon juice, garlic and caraway seeds to the beans and puree. Stir in coriander. Dab meat dry. Heat 2 tablespoons of oil in a large pan and fry the steaks for approx. 5 minutes, turning them over.
Season with salt and pepper. Arrange puree and steaks on plates. Garnish with coriander and physalis.
