Oysters Rockefeller
115 kcal a serving, against 275 for the traditional version. That is 160 kcal off, or 58%, with 5.6g of protein. Serves 4. 45 minutes.
What the traditional version is
The classic starts with a dozen oysters on the half shell, each topped with a mix of 100g softened butter, 60g breadcrumbs, 100g spinach, 40g parsley, 10g tarragon, 2 shallots, and a splash of Pernod. You blitz the herbs, spinach and shallot, work in the butter and Pernod, fold in the breadcrumbs, and thickly smear the paste over the oysters. After a quick blast under the grill, the top goes golden and the butter underneath keeps everything lush and silky. Serve on a bed of salt or crushed ice if you're doing things properly.
What changed, and what each change costs
Butter out, olive oil in
Butter is the main event in the original, but replacing it with a trace of olive oil means you still get a little fat to carry the herbs. It isn't the same - I'll admit the obvious - but at least you aren't left scraping oil off your lips.
What it costs you. You lose the thick, lush base that makes the topping behave like a sauce. What you gain is a fresher, cleaner sort of oyster, but don't expect velvet.
Bulk up herbs and spinach, cut breadcrumbs
Turning up the spinach and herb content gives you more green, more punch, and more topping - as well as far more vitamin content. Dropping the breadcrumbs keeps carbs lower and brings up the protein per serving.
What it costs you. Crust is the third casualty of this swap. The traditional version gets its golden, crunchy lid from a pile of breadcrumbs bound with butter. Here, you get a soft topping with a bit of colour, but not much crunch. If anyone complains, just tell them to chew louder.
Pernod held steady, oysters up
You really can't cheat the aniseed note or the brine in this one, so keep the Pernod (or a similar aniseed liqueur) and don't skimp on the oysters. I've gone for three per head, slightly up, to boost the protein properly and make up for the lost bulk from less butter.
What it costs you. The plate feels lighter, but you still get to taste the sea and some punch from the herbs. The protein content rises, so at least your sense of duty gets a treat.

The method is in the book
You can't pretend this is as decadent as the original - it's a cleaner, fresher way to eat oysters rather than a butter bomb in a shell. If you crave the velvet crust, look elsewhere. The upside is the flavour of the sea sings louder, and you can eat one or two more without feeling like you've just eaten your house deposit. If decadence is non-negotiable, bring back the butter, but don't blame me for the consequences.
