Grapefruit - currently at its best seasonally right through to May.
Often underrated (especially if you've been around long enough to remember it as a begrudged diet food of the 80's) but it's actually a bit of a secret star. With a sweet/tart taste and at 82 calories per globe it's versatile and packed with anti-oxidants and vitamin C which gives your immune system a boost. It also contains naringin which scientists say increases metabolism, so it helps your body to store less fat. It's also beneficial for heart health.
Of course you can just eat it as it comes, but it can be used as an ingredient. Below is a Mary Berry recipe for tomato and citrus salsa that can be eaten alongside fish, chicken or grilled halloumi.
half cucumber, deseeded and finely diced
1 green chilli, finely chopped
6 large tomatoes
1 pink grapefruit
1 lime, juice and finely grated zest
2 tsp freshly grated ginger
3 tbsp olive oil
3 heaped tbsp mango chutney
handful of chopped coriander
Chop all the ingredients.
Put them all into a bowl, apart from the coriander, and mix together. Season with salt and pepper.
When ready to serve heat gently in a pan, add the coriander and serve.
