This rice custard tart is a delicious combination of a creamy, vanilla-flecked rice pudding with a caramelised top all baked in a crisp shortbread crust. It's the perfect cure for the winter blues. Rosy-cheeked children returning home from the cold will be overjoyed at the sight of this belly-warming tart. I first spotted this tart while skiing in Valle d'Aosta and despite having a slice at lunch every day for a week, still needed to crack this recipe when I got home. It took several attempts to get the right texture - creamy enough to ooze just the right amount but firm enough to hold itself in a tart form. The top should caramelise nicely like a Portuguese natas tart. I hope you love it as much as we do. Enjoy!
