Pour in the double cream and stir through the True Origin Dill Mustard, allowing the mixture to gently simmer until thickened and creamy.
Meanwhile, blitz the True Origin Garlic & Herb Cashews together with the breadcrumbs until you have a coarse crumb mixture.
Toast the crumb mixture lightly in a dry frying pan until golden and crisp.
Transfer the creamy leeks to a serving dish and generously scatter over the garlic and herb cashew crumb just before serving.
Serve warm and enjoy.
