I also have fond memories of many such breakfasts, while hiking from one B&B to the next in Scotland . . .

DH is from New England and complains that the British baked beans are too tomato-ey and don't have molasses . . . I guess it's just a matter of style.

IMHO, why try to south-westernize it? I say let the generous donor offer up something that is authentic to her background and of which she is proud. Perhaps a little card on the tables explaining what is on the plate, and play up the novelty as to why it looks different from what they would get at any other local restaurant. If none of these people have had the opportunity to travel to the UK, it might be a first step towards broadening their horizons.

More important is that she's able to get bacon the way it's sliced and cured in the UK vs. here.

Anyway, baked beans and blood pudding are hardly the center-pieces of the meal. The amount of beans and pudding you get make them more like condiments. Kinda sorta.
