Delia also makes no secret of her enthusiasm for certain products, including home-grown asparagus, Bramley cooking apples, pork from Lane Farm and Kelly turkeys and chickens.

If you are having trouble tracking down an ingredient, take a look at Delia's Recommended Stockists, which lists mail-order suppliers for some of the more unusual items listed in Delia’s recipes.

More of Delia's favourites are described in full detail in Travels with Delia, where she waxes lyrical about anchovies, balsamic vinegar, crème fraîche, salmon, Parmesan (Parmigiano Reggiano) and Marsala.

As well as good local shops, Delia is a great fan of farmers’ markets, which can often provide unusual ingredients, especially seasonal, locally available ones such as wet walnuts, cob nuts, wild mushrooms and samphire. For details of farmers’ markets in your area, contact the National Association of Farmers’ Markets on 01225 787914.

We have also put together a section on the site called Food Online. This lists, region by region, shops that supply various foods, from fish to fenugreek, sourdough bread to Stilton. Read it and you might discover a gem of a shop locally that is a great source of specialist, luxury or hard-to-find foods.
