Compound butters are SO easy to make - I love them! On this blog already I have a Mint and Basil Butter - perfect with lamb! - and a Blue Cheese Butter which I serve with steak. They take very little time to make, can be prepared in advance, and then look so pretty when sliced into coins and you get a wonderful cross-section of the ingredients.

This latest version uses a simple combination of wholegrain mustard and parsley. It is so full of flavor!

How to Make Wholegrain Mustard Butter

Place a room-temperature stick of butter in a bowl, together with some wholegrain mustard (sometimes called "old style"), finely chopped fresh parsley, salt, and pepper.

Use a fork to mash everything together.

Transfer the butter to a piece of plastic wrap (cling film), and form it into a log shape, wrapping the plastic wrap tightly around it.

Place in the fridge and let it harden again. The butter can be made up to three days in advance. When ready to use, simply slice the butter into coins and place it on your chosen vegetables or protein.
