Simple salads of fresh tomatoes are a highlight of summer. Look for bright and firm tomatoes with wrinkle-free skins that are not split, and have a sweet, earthy scent. If sold on the vine, choose a thick, strong vine with tightly attached tomatoes. It's best not to put tomatoes in the fridge as this will impair their flavour and texture. This fresh tomato and corn salad is a perfect accompaniment to summer barbecues, or try this slow-roasted tomato salad for intense tomato sweetness.
