This kaffir lime, lemongrass and chilli butter is such a handy little cooking ingredient. Use it in place of plain old butter in whatever you might be cooking.
Add the lime zest and chopped ingredients to the butter and mix well.
Tip out the butter onto clingfilm and shape into a log. Roll up tightly and twist the ends like a sweet wrapper. Store in the fridge for up to 3 days or the freezer for a month.
To use, just slice off as needed, as in the images and video.
