What to expect for Prince Harry, Meghan Markle's royal wedding menu

Prince Harry, 33, and Meghan Markle, 36, will wed at St. George's Chapel.

LONDON -- When a self-proclaimed California foodie marries into the British royal family, there’s at least one certainty: The traditional British wedding menu will get a serious upgrade.

Unlike at American weddings, on Saturday there will be a wedding breakfast served after the ceremony, basically a light lunch. And later Saturday night, there will be a smaller, more intimate sit-down dinner. (After that is when we’re hoping for taco trucks.)

For a country still rationing at the time, the menu was downright luxurious, starting with filet de sole Mountbatten, Philip’s family name, and finishing off with a Bombe Glacee Princesse Elizabeth.

The menu also featured, a Perdreau en casserole avec haricots verts et pommes noisette (braised partridge) and extremely rare out-of-season strawberries.

At his second wedding, Prince Charles and his now-wife, Camilla, the Duchess of Cornwall, opted for more of a drinks and canapés affair.

But Prince Harry and Meghan, may break the mold all together.

"I think there will be a really nice spring salad to start, they could actually go with a venison because in Windsor Great Park there are a lot of deer," Emily Few Brown, who runs the hip London wedding caterer, Spook Cooking, told ABC News.

"Dessert-wise, probably something chocolate-y or a lemon tarte," she added.

A quick Google search now returns dozens of recipes for lemon-elderflower cakes. (We thought this one looked scrumptious.)

But Meghan won’t be going out on a limb, finding out awkwardly whether the Queen approves of late night sliders. Rest assured, the monarch will still have her say.

“The Queen will have a big say in those menus,” ABC News royal contributor, Omid Scobie, told ABC News. “And those menus will have traditional ingredients, but will also include some of the more modern ingredients we know Harry and Meghan like."

He added: "It will be a real blend of all those flavors."

We’re hungry just thinking about it. No doubt the new member of the royal family will start spicing up tradition — one slice of lemon-elderflower cake, at at a time.
