This recipe, which is as good as it is simple, comes from Chun Kern, my friend from the Himalayan hills who now lives in the United States. You may eat this in sandwiches, on toast, take it on picnics (I always do) or use it as a stuffing for ‘turnover’-type patties made with store-bought puff pastry. It is excellent eaten plain with a variety of salads. Use a good-quality tinned tuna packed in oil. I do not drain it as the oil prevents the tuna from drying out. Also, a good curry powder provides a useful short cut.
