Is it mustard or a pesto? This one, you will have to try for yourself. A perfect blend of both our Traditional Pesto and honey mustard makes this a rich tangy yet sweet mustard base sauce. Use it like mustard and have it with chicken, steak or lamb dishes, on a sandwich, or over veggies. But it's also lovely when used like a Pesto as a dip, spread for pizza base or focaccia, through a pasta dish, or my favourite is over my roast vegetables - smear over the top 10 mins before they come out of the oven (or just mix through before serving).
