As soon as it comes out of the oven, brush the olive oil kept from cooking the courgettes over the top of the tart to glaze it. This will give it a more appetizing appearance that will impress your guests.
Remarks
This tart can be eaten cold, but it is much better hot or warm.
And to drink?
A summery wine for a summery tart: for example the freshness of a Domaine du Tariquet, that excellent Côtes de Gascogne white.
