Summery Grapefruit Tart

This quick and easy grapefruit tart is light, bright and so refreshing. Topped with toasted coconut and chopped almonds, it is perfectly sweet and tangy – just how grapefruits should be.

Grapefruit Tart

I know grapefruits are at their best in the winter. But they’re always available where we shop. And Red is a little obsessed with them so we always have them around. So I decided it’s time to get in on the action and bake something grapefruit-y.

Grapefruit tart

Instead of a cake, I decided to make a grapefruit tart. It’s summer after all and I wanted something light and refreshing. And refreshing, this is.

Grapefruit Tart

Creamy, not overly sweet, with a hint of that grapefruit tartness – a slice of this on a hot summer day will immediately cool you down (or on a cold winter day – cheer you up!) Don’t skip the toasted coconut and almonds – coconut with grapefruit is the flavour combination food dreams are made of.

Grapefruits are not acidic enough

I love key lime pie. So I initially thought I could just switch the citrus and use my eggless key lime pie recipe. But after much research I found that the acidity of grapefruit is lower than key limes (or lemons) so the pie will not set if they are subbed.

There were lots of ideas out there about how to address this including putting crushed vitamin C into the recipe. I was not comfortable with putting any kind of medicine into my tart so I settled on cornstarch. The original recipe asked for 3 tablespoons, which I thought was a lot but I promise you will not taste it in the tart.

Slice of the tropics

The only thing you will taste is deliciousness. Served cold and topped with toasted coconuts and chopped almonds, a slice of this tart is pure bliss. It’s luxuriously creamy, it has the perfect balance of sweet and tangy, the coconut lending crunch and a tropical flair.

I’m not a big grapefruit fan but I am a huge fan of this tart. If you manage to get a hold of grapefruits this season, grab a few and treat yourself to a unique tart with flavours that are hard to beat.

Instead of using vitamin c I would have gone with citric acid, I guess it would just take a pinch to get enough acidity to settle the milk. But then I would omit the aluminum foil because it reacts with the acid. Anyway the tart looks amazing and the roasted coconut adds a nice crunch to it.

Hi Ricky! Frankly I'm wary of putting those ingredients on the tart...I guess because they're not your usual baking ingredients? Though that's such a great insight on citric acid and aluminum foil. Perhaps I would try that next time :)

I am not much of a fan of key lime pie, but grapefruit? Yes, please! I wonder, would bottled juice work instead of fresh-squeezed?

Hi Kyla! I think bottled juice would work. As with KLP, some people prefer to use bottled instead of fresh juice. Just watch the sweetness or the acidity (sourness). Since they are concentrated their flavour will be stronger than fresh (I do recommend using fresh juice though :)
