Thank you for your reply - excellent knowledge of the Croquembouche!
I did laugh at the return to Lille advice! We are not looking for a majorly fancy croque, like some of the Antoinette-esque proportioned towers I have seen - although they ARE lovely, they scream, "Not in the budget, look the other way!" to me. Maybe I should just asj my catererer to stack up loads of profiteroles in a mountain and call it a cheats croquembouche!
I will def try the patiserrie on St John's Hill. I have enquired at the lovely Macaron patiserrie opp Clapham Common, but they are a bit tardy with a response!
Ears are flapping for anymore suggestions.
Many thanks for taking the time to sen d such detailed advice.
