I can't find the Jamie Oliver Sainso recipe but know it was dead simple - and everything I'm finding online looks a tad more confusing than I can be faffed with.
So will this work?
Butter the Hot X buns, put a blob of apricot jam on each, sprinkle over chopped dried apricots and sultanas, pour over a tub of vanilla custard and bake.
does that sound feasible?
