This is a great dish to make right now, when tomatoes and watermelon are at their finest, with the smoked yoghurt offsetting their natural sweetness. I often find this makes more than I need for the recipe but seldom have a problem using it up over the next few days. You’ll need to pay a bit of attention here – the heat must be quite low to ensure the yoghurt doesn’t curdle. I sometimes chill the bowl the yoghurt is going in, which also helps keep it cool.
The subtle smoky flavour of this yoghurt offsets the natural sweetness of the tomatoes and watermelon, making for a very refreshing late-summer salad.
