Stage 4 - ⌛ 40 min.
Each time you stir, remember to scrape the bottom of the pan to mix in the cooking juices that the onions will create, so that gradually...
Stage 5
...they will take on the desired colour and consistency.
At about halfway, you can remove and discard the thyme and bayleaf.

Stage 6
Once the onions have reached this colour (I like them really well caramelized), take off the heat, salt and pepper, then check the seasoning.
Stage 7
Your onion fondue is ready for use in any recipe you like.
Remarks
You will notice how the long cooking really brings out the onions' slightly sweet flavour, so do salt quite generously at the end of cooking.
It is important not to use a non-stick pan, as a conventional metal pan helps the onions to stick and create the cooking juices. These should be scraped off the bottom frequently and mixed in.
You can use clarified butter instead of the mix of oil + butter, or just normal butter, but take care not to let it burn.

These little tarts taste every bit as good as they look. The sweetcrust pastry cases are filled with a layer of stewed apple and topped with a blackcurrant crémeux. This offers your guests a delightful element of surprise, as the apple flavour is only discovered as they eat it (but only if you've been secretive, of course). October 10th 202147 K 1 hour 8 min.
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.

Pilau rice
Pilau rice (also called "restaurant rice" in France) is a way of cooking rice that's very different from using a rice-cooker. In this recipe, the rice is first "pearled" with onion in olive oil, then chicken stock is added, and the whole lot is put in the oven. This produces a very tasty moist rice, which can easily be kept waiting without drying out. February 21th 2011407 K 14.4 35 min.
