Cucumber Raita

This is my normal go-to raita, not quite sure why I do this so often rather than the tomato one. You could always put tomato and cucumber too, of course.

Half a long cucumber (partly remove the peel, in strips, and slice finely)

1/2 teaspoon mustard powder

1/2 teaspoon salt

1 green chilli, slit along its length

Small handful coriander leaves, torn up

1 standard pot of yogurt (1/2 litre?, stirred up so no lumps)

Mix all ingredients into a bowl, stirring well. Leave it standing for a while to let tastes blend in. Before serving, remove the chilli. Garnish with coriander leaves.
