Bouquet garni
Bouquet garni
Used very frequently in French cuisine, a secret of French chefs, it adds flavour to a lot of recipes, and it's easy to prepare. The basic principle is to make a small bundle of herbs, bind them in green leek leaves and to tie it up, so that the whole thing can be removed and discarded easily after cooking.

The French make a "tourte" that is smaller and deeper than a normal quiche. This recipe makes the most of this difference: it has plenty of texture and flavour, with bacon, potatoes, leeks, two different cheeses, and an egg and cream filling poured over.

  • This looks like a cake I will make and thank you for the recipe. As for the slit in the top, this happens to my cakes naturally! I use the convection oven inside the microwave and this is always the result. At least they look "home made" when I gift them which is nice. Do you have any comments on the preparation of fruit you wish to zest? I wonder sometimes it I'm zesting chemicals but don't want to scrub too hard.
