Four French Kitchen Gadgets Tested: Escargot Dishes, Clef Du Vin, Saucisson Guillotine and a Grill Stone

Introduction

French kitchen culture has produced more than its fair share of specialised gadgets, and four in particular stand out for anyone who enjoys cooking and entertaining with a bit of theatre. We put a pair of vintage escargot dishes, the Peugeot Clef Du Vin wine-aging key, a domestic saucisson guillotine, and a Pierre a Cuire grill stone through their paces in a real kitchen. Some earned instant affection, others raised eyebrows. Here is how each one performed and who they actually make sense for.

Vintage French Escargot Dishes

This pair of escargot dishes is handmade in France from Amber Brown stoneware ceramic, and each dish features a handle plus six rounded wells designed to keep snails, sauces, and seasonings perfectly in place. The concept is simple: instead of baking escargot in a loose pan where garlic butter spreads everywhere, each portion sits in its own controlled pouch, cooks cleanly, and then goes straight to the table as an individual serving.

To test them, snails removed from their shells were braised in stock for 45 minutes, combined with a compound butter of butter, garlic, and parsley, returned to their shells, and nestled into the wells. Twelve minutes at 180 degrees C in the oven later, the dishes delivered exactly what they promise: the butter stayed contained in each little pouch, the presentation looked genuinely inviting, and the snails cooked evenly.

The strongest verdict of the whole lineup came from this test. As a way of controlling butter, cooking, and presenting escargot per person at the table, it simply works, and it turns a normally messy dish into something you are happy to serve guests. At 16.99 for the pair, it also proved to be remarkable value. The one caveat worth noting is that the escargot pickers, sold separately, do much of the fiddly work, and some garlic butter does end up lost to the well as you extract each snail. If you like snails and want to serve them properly, this is a fantastic way to present them.

Peugeot Clef Du Vin

The Clef Du Vin from Peugeot is the result of ten years of research and a registered patent, and it claims something almost implausible: dip this small alloy key into a glass of young wine, and every second it is immersed ages that wine by one year. The small nub on the end acts as a catalyst for oxidisation, forcing sulfur compounds and tannins to react with oxygen instantly. Two use cases are pitched: buy younger wines and age them in the glass for immediate drinking, or sample an expensive cellar wine through the cork to judge how many more years it needs before opening.

Testing across a 12 pound red, a Chardonnay, and a 20 pound 2020 vintage produced genuinely noticeable but inconsistent results. One red became richer and more rounded, moving toward something you would happily pair with steak. The Chardonnay came alive, fresher and more vibrant. A different red turned grippy and, eventually, flat and vinegary once pushed past its ideal, which is how the device signals you have gone too far: when the wine suddenly tastes acidic or metallic after two seconds in your mouth, you have crushed it.

That inconsistency is the core problem. Sometimes it appears to improve a wine, sometimes it dulls one, and the effect is not always obviously an improvement. For serious wine collectors or anyone running a vineyard, being able to preview aging potential could save real money on bottles opened too soon. For everyday home drinking, it is harder to justify. It retails at 36.60, and opinions landed between two and a half and three and a half stars: it clearly does something, but its everyday value is debatable.

Saucisson Guillotine

Of course a French gadget roundup includes a guillotine. The Saucisson Guillotine was originally designed to solve a real problem for butchers and delicatessens: slicing large quantities of dry sausage quickly, uniformly, and without fatigue. This smaller version is aimed at domestic use, positioned as the centrepiece of Apero, the French tradition of pre-dinner drinks and snacks.

The design is what makes it effective. Because the serrated blade is mounted on a sliding track, it creates a sheer force with a back-and-forth cutting motion rather than simply pressing down, which keeps the slices perfectly round instead of flattening the sausage. In testing it sliced cleanly through saucisson and a range of cured meats from soft to very hard with essentially no effort, producing lovely thin, even slices. The makers also claim it can handle small cheeses, firm vegetables, breadsticks, and other snack board items.

Two practical notes: it is made of beechwood, so it is hand wash only, and it is right-handed, which limits who will find the smooth slicing motion comfortable. It would also benefit from some sticky feet, as it can feel a little slippery on a worktop. At 45.73 it is a single-job gadget, which is usually a red flag, but it does that job so well and turns your daily routine into a bit more of a ritual. It scored the second-highest of the group.

Pierre a Cuire Grill Stone

The Pierre a Cuire is a grill stone designed for larger or shared portions, aimed at tabletop grilling at restaurants or dinner parties. It includes a support tray and stand for stability and heat insulation, and the method itself is a French tabletop cooking tradition said to date back to medieval times, where everyone cooks their own food at the table to their preferred doneness. The claim is that the stone preserves the natural flavour of food because it is a clean cooking method.

The process involves preheating the stone in a full-heat oven for 20 minutes, then maintaining temperature with a small lit pot of gel underneath to keep it hot while you talk and eat through the evening. In practice, the results were underwhelming. The stone heated, the first side of the beef cooked relatively quickly, but the whole thing cooled down significantly after a short while, and the second side took noticeably longer. After about ten minutes it was no longer getting hotter, effectively just resting the steak in its juices.

The main lesson from testing: cut thickness matters enormously. Thin minute-steak style slices would work far better than chunky pieces, and for a single person you would realistically want a couple of these stones going at once. Among hot stones of this type, the presentation is one of the smarter takes on the format, and the social, cook-it-yourself appeal is real. But the heat simply does not hold long enough to cook something properly; you are always working on residual heat and never quite getting the best result. At 96.78 once converted, it is also the most expensive item here, which makes the performance gap harder to forgive.

Buying Advice

If you only buy one of these, the escargot dishes are the standout: affordable, charming, and they solve a genuine serving problem beautifully. The saucisson guillotine is the best pure tool of the bunch for anyone who regularly entertains with charcuterie, provided you are right-handed and happy to hand wash beechwood. The Clef Du Vin is a fascinating curiosity best suited to wine enthusiasts and collectors who will actually use the aging preview, while the Pierre a Cuire makes sense only if you are committed to the tabletop cooking ritual and plan to use thin cuts and possibly more than one stone.

Conclusion

Four gadgets, four very different verdicts. The escargot dishes delivered a full-mark performance by doing one thing with real charm, the guillotine proved a single-job tool can still earn its counter space, the Clef Du Vin is clever but hard to value at home, and the grill stone looks smarter than it cooks. Match the gadget to your actual table habits and you will not go far wrong.
