Step by step recipe


Stage 1 - ⌛ 30 min.
How to prepare cockles : Stage 1
Tip the cockles into a large container of cold water. Stir them round briefly and leave for 30 minutes.

Stage 2 - ⌛ 3 min.
After this time, remove the cockles form the water. It is important not to tip the contents of the container through a sieve (which will not extract the sand), but remove them carefully from the water.

See how on this video.

Discard the water, rinse out the container, refill it with clean water and put the cockles back in.

Stage 3 - ⌛ 30 min.
How to prepare cockles : Stage 3
Leave to soak for another 30 minutes.

Repeat this operation until the water remains clear.

Stage 4 - ⌛ 5 min.
How to prepare cockles : Stage 4
Chop 1 shallot.

Rinse the parsley, keeping the stalk.

Stage 5 - ⌛ 2 min.
How to prepare cockles : Stage 5
Melt 10 g butter in a large pan then add the chopped shallot and parsley, but do not add salt or pepper. Cook without colouring for 1 minute.

Stage 6 - ⌛ 5 min.
How to prepare cockles : Stage 6
Add 100 ml dry white wine and bring to the boil.

Stage 7 - ⌛ 2 min.

Stage 9

After a few minutes, the shells will begin to open. Stir them round in the pan so that those that are still closed are in the wine to give them the chance to open.

Stage 10 - ⌛ 5 min.
How to prepare cockles : Stage 10
After 3 or 4 minutes take out all the opened cockles, using a (spider) araignée or skimmer and put them in a sieve.

Stage 11 - ⌛ 10 min.
How to prepare cockles : Stage 11
Remove the contents of the cockles one at a time and discard the shells. Discard any cockles that have broken shells and any that have not opened.

Stage 12 - ⌛ 2 min.
How to prepare cockles : Stage 12
Rinse the cockles under cold running water to remove any remaining sand.

Stage 13
How to prepare cockles : Stage 13
If you plan to use the cooking liquid to make a sauce, which is a very good idea, you will need to reduce it.

Stage 14 - ⌛ 3 min.
How to prepare cockles : Stage 14
Pour the contents of the pan into a smaller pan through a fine sieve.

Stage 15
How to prepare cockles : Stage 15
Beware: the sand from the cockles will collect at the bottom of the pan, so it is important NOT to try and filter right to the last drop, but discard the liquid from the bottom (and the sand with it).

Stage 16 - ⌛ 15 min.
How to prepare cockles : Stage 16
Reduce the remaining saved cooking liquid by around half over low heat before using in your recipe.
Remarks
When preparing cockles, you will encounter two problems: sand, which is very unpleasant in the mouth (so do follow the advice to deal with this) and the saltiness of the cooking liquid. If you use this to make a sauce, do not add any salt.

Cockles are mostly shells and water: for 1 kg of cockles you will only end up with around 100 g of useful cockle meat (90% waste).
Keeping: A few hours in the fridge in a sealed container or covered with plastic film.

Leaven is a natural raising agent, a fermented mixture of water, flour and the microscopic yeasts which are present in the air. It's a delicate living substance, sensitive to the external environment.

How to glaze a tart
How to glaze a tart
Professional pastrycooks usually say that "a beautiful cake is already half sold", it is one of the reasons why they do not put a tart on sale without glazing it ("abricoter" in Fench), i.e. coating it with a thick apricot syrup. This glaze gives a glossy finish to the tart (see the photographs below) and also protects it from the air and thus from oxidation and browning. It's a quite simple technique that you can easily apply to give to your desserts a professional look. This is how you do it.
