Morrisons Mint Sauce - 180g

Mint sauce belongs to the Sunday roast the way Yorkshire puddings do: not strictly required, absolutely expected. Lamb gets mint, beef gets horseradish, and in most British kitchens that is not up for discussion.

You can cook a cracking roast anywhere. It is the bits on the side that give away where you grew up, and a jar of supermarket mint sauce from a British high street is exactly the sort of thing you do not realise you miss until the lamb is carved and something is wrong.

It comes in a 180g jar, ready to spoon straight out, with no chopping or steeping. It lives in the cupboard until opened, then check the label for how to keep it. A little goes a long way, so one jar sees off a good few roasts, plus the odd lamb chop, a spoonful over peas or a dab on a shepherd's pie.

Morrisons is one of the big British supermarkets, and its own-brand jars are everyday stock in a UK cupboard. Put this in the basket next to gravy granules, a jar of horseradish and some Yorkshire pudding mix, and the whole roast is sorted.
