Jean Michel Raynaud
It will take around 20min to mix and pipe the macaron and 30 min to cook them. About the same for the caramel. Then cool the macaron and fill them up.
You cannot eat them straight out of the oven, they need to sit in the fridge overnight at least, depending on the fillings.
The salt needs to dissolve slowly in the toffee to get the balance of flavours right, and the shells of the macarons need to reabsorb humidity from both the filling and the fridge.
