We have Laduree branch in London and also Paul's bakery - both of which have macarons.
When we had the costumed event here in the UK a fortnight ago, someone brought up macarons from Laduree in London. One of them was ROSE!! It was sublime. Very buttercreamy initially and then one got the gorgeous after taste of pure rose. And one could "smell" it at the same time.
I now need to find some really good rose flavouring to replicate that.
Thanks for your post.
