Of the dozens of ways to make a sponge, most make use of an egg or two, or three, or maybe even a boxful. Here there are none.
But it’s not just about what this sponge does without. It’s also about what it does with. Yes, it has the expected flour, caster sugar and butter, but it also has the more unexpected condensed milk, orange juice and vinegar.
As for the filling, what could be more peaches and cream than peaches and cream?
