When in Yorkshire...
Henderson's Yorkshire sauce, handmade in Yorkshire. Looks like it'd be similar to Worcestershire sauce.. And in a way it is, only it's a tad mushroomy.
The crisps have a good crunch and are well salted with skins on the edge.
There's a slight sweet tang to these. Strangely since it's not in the ingredients- it tastes a little like soy sauce, I guess it's the mushroomyness of the sauce. An interestingly different flavour.
