First blanch all the herbs for around 20 seconds. This might seem short, but otherwise the coulis will turn brown. Now cool the herbs in ice water.
Then let the herbs drain for at least 10 minutes, you don't want any blanching water. Giving the herbs a good squeeze also helps.
Meanwhile cut the shallots in half and clean them. Now chop them.
Then add a drizzle of oil to a hot pan and glaze the shallots on a low heat. Add some salt for seasoning and to help softening the shallots.
Once softened add the vegetable broth and then let it cool down in your fridge.
Then transfer the herbs into a blender and also add the shallots & broth. Blend this till completely smooth. This can take a couple of minutes.
After that pass it through a fine sieve. Using a ladle will make this a lot easier. The result is a base coulis, but it’s already delicious like this.
