The marinade is composed of paprika, turmeric, cumin, coriander, cinnamon, garlic, black pepper and salt. The colours that stand out the most are perhaps from the paprika and cinnamon (reddish tones) but the grilling technique is also responsible: high heat without excessive burning/charring of the meat (I like to singe the fat for extra flavour).
Just back from a great break with very good food……we are not skilled enough or have all the ingredients to hand.
But last year….a different hotel, they really made a big fuss of the chef cooking the steak over an open fire in front of us. Worst steak i have had in decades……home or restaurant.
