Place a wok on a high heat and add the oak wood chips. Once the wood starts to smoke, add the raspberries. String the cockles together with a needle and thread. Suspend the string over the wood chips and cover with a lid. Leave to smoke for about 5-6 minutes. (CAUTION: Food-smoking generates a great deal of smoke. Cook in a well-ventilated place and open the windows.)
Remove the cockles and de-string.
Toss the cockles in the semolina flour. Heat a high sided frying pan until hot then add enough olive oil to cover the bottom of the pan, 2cm/½in deep. Add the cockles and shallow fry for one minute. Remove and drain onto kitchen paper.
Meanwhile, for the creamed corn, heat a frying pan until warm then add the olive oil.
Add the shallots and sweat for one minute until soft but not coloured. Add the sweetcorn and white wine, and cook until the wine is reduced by half.
Add the double cream and again reduce by half. Season to taste and remove from the heat.
Place the lemon segments, celery leaves, parsley and olive oil in a bowl and mix together. Season to taste.
To serve - place a spoon of the creamed corn in the middle of the plate, place the salad on top and top with the smoked cockles.
