Invalides Extra French Walnuts 500g

French extra halved walnut kernels are the reference we've carried on our shelves for years, serving pastry chefs and home cooks alike who want a clean, ready-to-use French walnut — no skins, no fuss, nothing added. The legal designation "cerneaux de noix moitié extra français" follows professional nomenclature: "moitié" refers to the kernel split into two regular halves.

This 500 g bag is a workshop-friendly format — enough for two to three walnut cakes or a week's worth of garnished salads. The "extra" grade corresponds to the top tier of commercial sorting.

What the French classification means

French walnut kernels are sorted into several regulated categories: extra, premier choix, and lower commercial grades. The "extra" designation covers the palest, most intact kernels — no broken pieces. This is the quality you want when you need a visible garnish or a polished presentation.

Origin: France. French walnuts come primarily from two production areas, the Périgord (AOP) and the Isère (AOP Grenoble). The label on this package does not specify the exact region, listing simply "France" as the generic origin.

Walnut cultivation in France dates back to the Gallo-Roman era. The two national AOP designations (Périgord and Grenoble) shaped the industry through the 1990s and 2000s, but conventional non-AOP production still accounts for the majority of volume and supplies most commercial kernels. French traceability remains a meaningful advantage over Chinese or Californian imports.

Ways to use them

The classic walnut cake is the go-to recipe — 200 g of kernels for a family-sized loaf, folded into a butter-sugar-egg-flour batter with a little baking powder. Bake for 45 minutes at 170 °C. Reserve a few whole halves to press into the top for a clean finish.

For an autumn salad, use whole or roughly chopped kernels with Belgian endive, blue cheese, green apple, and a walnut oil vinaigrette. The endive-walnut-blue cheese combination is a classic from northern France that never goes out of season.

For fine pastry work, toast the kernels for five minutes at 150 °C before use — it wakes up the aromatics and softens the tannic bitterness characteristic of French walnuts.

For a quick homemade walnut oil, toast the kernels for 10 minutes at 150 °C, blitz in a food processor, then press through a clean cloth. Yield is modest, but the freshness of the resulting oil is unmatched. Use within the week for vinaigrettes or as a finishing oil over cold dishes.

France's walnut-growing regions have diversified considerably over the past twenty years, with selected varieties such as Franquette, Mayette, and Marbot each offering a distinct aromatic profile. The generic "extra France" designation typically refers to a varietal blend that balances those characters.

The term "moitié" (half) comes from the fact that a classic French walnut naturally splits into two halves when opened — each corresponding to a cotyledon, the botanical term for the seedling's first leaves. Commercial sorting distinguishes whole halves (extra) from smaller pieces (brisures and milles).

Delivery across France and storage

Available in a 500 g bag, for in-store pickup at our Paris location or shipped anywhere in France. Store at room temperature, away from heat and humidity. Once opened, transfer to an airtight jar: French walnuts go rancid faster than almonds, especially after toasting.

The 500 g bag covers approximately two family-sized cakes or three to four autumn salads. For regular workshop use — walnut cake, walnut tart, bread — larger bulk quantities are available under other references on our shelves.

For lovers of AOP Noix de Grenoble or AOP Périgord walnuts, we carry dedicated references in separate bags. This generic "extra France" reference offers the best value for everyday use without the AOP premium. Both have their place depending on your budget and intended application.

Frequently asked questions

What is the difference between French walnuts and pecans?

French walnuts are more tannic, more bitter, and more structured on the palate. Pecans are milder, oilier, and more tender. The two are botanically distinct and come from entirely different trees.

Can I substitute broken walnut pieces?

If the walnuts are going into a batter or a salad, broken pieces work perfectly well and cost less. For decorating a cake or a polished plating, whole extra halves make a noticeably better visual impression.

How do I reduce the bitterness of walnuts?

A light toasting — five minutes at 150 °C — is the simplest method. Alternatively, soak for ten minutes in warm water, then dry in the oven. Toasting is the most straightforward approach.

How long do they keep after opening?

Six to eight weeks in an airtight jar kept in a cool, dry place; three to four months in the refrigerator. French walnuts go rancid faster than most other nuts due to their high omega-3 content.

Are they suitable for a gluten-free diet?

Walnuts are naturally gluten-free. However, gluten-free certification is not guaranteed for this specific bag — check the label if you have a confirmed sensitivity.

Are they more affordable than AOP kernels?

Yes, noticeably so. AOP Périgord or AOP Grenoble kernels typically run 20–30% higher than generic extra France kernels. The aromatic difference exists but remains subtle when the nuts are incorporated into a batter. For garnishing or straight snacking, the AOP designation carries more weight.
