Homemade Mint Sauce tastes infinitely superior to shop-bought versions, and takes 5 minutes to make. All you need to do is boil the kettle! Here's how to make this classic British condiment.

A classic mint sauce is traditionally served with roast lamb, and it has a strong flavor of mint and a hint of acidity from vinegar. It's essential to get the balance right and take the edge off with some sugar. It was actually introduced to England by the Romans, so in that sense it is not British at all. But it is so ingrained in our culture that we have sort of adopted it.
What kind of mint for mint sauce?
Apple mint is the best mint for mint sauce, in my opinion. That's the one with larger, pale green, fuzzy leaves. However, most shops will sell Moroccan mint, which is the one with slightly smaller, slightly darker green leaves with no furry texture to them. A lot of recipes call for spearmint, which is the one with pointy leaves and a scent that clears your airways (like breathmints or toothpaste).
And this is all fine, but not optimal, in my (British) opinion. I circumvented this issue by growing my own apple mint, as it is my personal favorite. But use whichever variety of fresh mint you can get your hands on. And don't use dried mint.

How to make mint sauce from scratch
- Finely chop your fresh mint leaves and place them into a heatproof bowl.
- Pour boiling water onto the mint to just cover it, and add a pinch of white sugar. Stir to dissolve, then put the bowl in the fridge to cool it rapidly.
Measure in the same amount of white wine vinegar, and season with salt and pepper. And that's it! There should be a fair amount of liquid in the bowl. When people serve themselves they can strain this off if they like.
