Tuscan Rice Tart

The two flours in the pastry are a compromise, not a style choice. Wholemeal alone makes a dough that's heavy and crumbly — too much bran cuts the gluten strands short, so it won't hold a tartlet shape when you unmould it. All plain flour gives you a shell with no character against a sweet, orange-scented filling. Half and half gives enough structure from the plain flour and enough texture and faint nuttiness from the wholemeal to actually taste like something next to the custard. If you've only got plain flour in the house, use it — the tart won't suffer much, it'll just be quieter.

The butter in the pastry wants to stay cold and get rubbed in, not melted and stirred in — rubbing coats the flour grains in fat before any liquid arrives, which is what keeps the dough short rather than tough. In a British kitchen this is the exact same logic as shortcrust for a jam tart; nothing exotic here, just the same mechanism dressed with orange zest instead of nothing.

Pudding rice is doing a specific job: it's a short, round-grain rice bred to release starch and go creamy under slow cooking, the same family as the rice you'd use for rice pudding on a Sunday. Basmati or long-grain will not behave the same way — the grains stay separate and the filling won't bind, it'll just be custard with grains of rice floating in it rather than a cohesive mass. If pudding rice isn't to hand, arborio (risotto rice) is close enough in starch behaviour to substitute.

The milk, split across two stages — 600ml for cooking the rice, 200ml for the custard — is simply there because rice needs a generous amount of liquid to cook through gently without catching, while the custard needs only enough to carry the egg yolk and flour into a pourable cream. Don't be tempted to use less for the rice stage; a saucepan with too little milk and a lot of starch scorches on the bottom before the rice is tender, which is the actual reason recipes tell you to stir regularly rather than walk away — not fussiness, just physics on a domestic hob where the heat isn't as evenly spread as people assume.

The vanilla pod appears twice for a reason worth noting rather than ignoring: it's infused once in the rice-milk, then — "empty," the recipe says, meaning already scraped of seeds — infused again in the custard milk. Nothing wasted. One pod, two jobs, because vanilla pods are expensive and a Tuscan pastry cook isn't going to throw out a perfectly good husk after one use. If you don't have a pod, a small spoon of vanilla extract added at the same point in each stage does the job, just less quietly.

The orange zest, going into both the pastry and the custard, is the flavour spine of the whole thing — citrus against dairy and starch, which otherwise risks tasting like not much at all. Some versions use lemon zest instead or alongside; use whichever your orange smells more interesting, because a tired supermarket orange with a thick dull skin gives you bitterness from the pith and little scent from the oil. Zest only the coloured skin, nothing white beneath it.

Resting the dough for an hour in the fridge isn't tradition for tradition's sake — it lets the gluten that did form while mixing relax, so when you roll it out to line small tins it doesn't spring back and shrink in the oven, leaving you with tartlet cases shorter than their filling. Skip the rest if you're short on time and you'll mostly notice it at the edges of the tins, where shrunk pastry means the custard overflows and catches on the metal.
