I pretty much like all fruit - but especially citrus. Also, where the heck is passionfruit on there?!
I think my favourite would have to be the humble lemon though, because it's so diverse! You can make lemonade which is delicious, lemon cake which is delicious, use it to flavour so many things and make them delicious. Lemon candy (especially sherbert lemons) are amazing! Also lemon smells wonderful and is an odour nuetraliser so if your fridge is stanky use lemons to clean it, use lemons to rid the garlic stench from your hands after chopping garlic and onions. Add lemons to honey and get a cure for sore throat. It is good for digestion alongside it's sister the godly LIME. Lemon is good in facial treatments because it zaps away acne. It can also LIGHTEN YOUR HAIR. And one last thing, you can dry out lemons in the oven to make Christmas decorations which have the bonus effect of making your house smell totes amaze.
LEMON POWER.
The same can be said for limes too, which are also smurfing delicious. GIVE ME ALL THE LEMONS AND LIMES.
