1. In a small pan, add 100ml of olive oil and the sliced garlic and bring to frying temperature over medium heat. Stir occasionally to keep the garlic slices separate and so they cook evenly. Fry until very pale golden (don't overcook or they'll be bitter) then remove and drain on a paper towel.

2. Slice the iceberg lettuce finely, chop the avocado into one-centimetre dice and arrange both on a shallow platter.

3. Heat a large frying pan over high heat. Dress the prawns with a splash of olive oil and season with salt and pepper. Fry in two batches for about three minutes each or until just cooked.

4. Place the prawns on top of the lettuce, squeeze over some lemon juice and scatter over the pea shoots.

5. In a small pan, add the anchovies and a little of their oil and mash over medium heat. Let them dissolve slightly, then add the creme fraiche and mix through briefly. Take off the heat and mix thoroughly.

Spoon the dressing over the prawns, scatter over the crisp garlic and serve.

Tip Cooking the garlic slices by starting them in cold oil helps them to cook evenly and slowly; burnt or bitter garlic will ruin the dish.
