Rhubarb and custard tart, tangy and sweet rhubarb on a bed of creamy homemade custard. The perfect way to take advantage of rhubarb season!  

We’re smack bang in the middle of rhubarb season and this rhubarb and custard tart is the best way to take full advantage of this early summer treat. Rhubarb has quite a short season here in the UK, which runs from April to late June. Unlike most other fruits, it’s quite difficult to get outside of season. You need to take full advantage of this bright pink gem while it’s around. Rhubarb is best eaten when it’s at its ripest. Which is when it’s that beautiful bright pink hue, which creates a stunning effect in this tart.  

My parent have an allotment where they grow their own rhubarb. And when I say grow, I mean it grows everywhere! Every year we give away kilos and kilos to friends and family, we make pies, tarts, jams and even our homemade rhubarb gin! We even manage to freeze enough to last us all year. I don’t know how they do it, it just grows like crazy.

This year to try and mix things up a little, I’ve decided to use up my personal rhubarb stock with this rhubarb and custard tart. Tangy and sweet rhubarb on top of a thick vanilla custard, it tastes just like the sweets! I haven’t had a rhubarb and custard sweet since I was a child. What actually inspired this tart is a rhubarb and vanilla flavoured water that Tesco have. I bought it on a whim even though Sam hates rhubarb and it tasted so much like the sweets I used to have when I was little. I just had to run to my mums and grab some rhubarb and start baking.  

This recipe calls for 375g of sweet shortcrust pastry, you can buy a readymade pastry case, buy your pastry from the store or you can make you own with my recipe here. It’s all good!
