What the traditional version is
This is the kind of pie you make for a reunion, not a Tuesday. The base is shortcrust pastry from 250g plain flour and 125g butter. For the filling: 225g caster sugar, 125g melted butter, 4 whole eggs, 350g buttermilk, a splash of vanilla, and 100g double cream. Bake it until it just sets to a wobble.
What changed, and what each change costs
Butter in pastry and filling to half-fat yoghurt and a splash of oil
Butter gives you that rich base and mouthfeel in the custard. Swapping it for yoghurt gives you the tang and some protein, with only a little fat for structure from a splash of vegetable oil.
What it costs you. Shortcrust isn't the same: it's a bit more cardboard than biscuit, and the filling misses that 'set and melt' texture. The custard will never be as lush, but you do get a little tang and it holds a slice.
Caster sugar cut by half
You still need enough sugar to keep the eggs from setting into a frittata. Dropping it to 110g isn't exactly hair-shirt, but the pie is much less sweet than you expect.
What it costs you. It's less pudding, more breakfast. Eat it cold and your teeth won't tingle.
Whole eggs up, double cream out, plus a little whey protein
Double cream makes a custard rich, but if you add another egg and a gentle scoop of whey powder you get more body and much more protein. Don't go wild: too much and the filling goes rubbery.
What it costs you. If anyone says they love this more than the original, they're lying or they've just finished a half-marathon. Still, it cuts clean and you get more than a breath of the real thing.

The method is in the book
The original is pure decadence: soft, tangy, sweet, and soaked in butterfat. This one is only two of those four. It scrubs up well enough, but it isn't a pudding for showing off. You get a slice you can pick up, you get a bit of tang, and you get plenty of protein. The price is paid in mouthfeel - the original is creamy, this is just set. If you can't face a full-fat pie, this is a fair nod to the spirit, but no one ever lied to themselves with a spoonful of this and believed it.
