I've adapted this from a Jamie Oliver recipe. Jamie makes it with his 'flavour shaker' but as most people probably don't have one - you can use a mortar and pestle. Use this marinade for steak, chicken or fish. It imparts a wonderful flavour. We had it with steak and it made it beautifully moist and tender and lemony - quite a different taste for steak but absolutely delicious! Quantities given should make enough to marinade 2-3 steaks or 2 large chicken breasts or 4 fillets of fish.
