Sirop De Groseilles
"Prenez jus de groseilles, deux livres un quart; sucre, quatre livres. On choisit de belles groseilles rouges, on les égrène, on les pile légèrement dans un mortier de marbre, on jette le marc sur un tamis; quand il est égoutté, on le soumet à la presse; on met le jus dans une terrine de grès, on l'y laisse jusqu'à ce qu'il commence à fermenter; alors on le passe à la chausse de drap; on en pèse la quantité prescrite; on pèse du sucre en proportion, on le clarifie et on le fait cuire à la grande plume, c'est à dire jusqu'à ce qu'en secouant l'écu- moire imbibée de ce sucre il s'en détache en grands flocons abondans qui ressemblent à des barbes de plumes; on y jette le jus de groseilles, on fait jeter deux ou trois bouillons, et le sirop est fait. Le sirop de cerises se fait de la même manière, si ce n'est qu'il n'est pas besoin de laisser fermenter le jus, et qu'on en met une livre juste pour deux livres de sucre. Ces sirops, ainsi que tous les autres sirops acides, doivent être préparés dans une poêle ou bassine d'argent."
English Translation
"Take two and a quarter pounds of red currant juice and four pounds of sugar. Choose beautiful red currants, remove their stems, and lightly crush them in a marble mortar. Place the pulp on a sieve; once it has drained, press it to extract more juice. Pour the juice into a stoneware bowl and leave it there until it begins to ferment. Then, filter it through a cloth strainer. Weigh the prescribed amount of juice and, in proportion, weigh the sugar. Clarify the sugar and cook it to the 'grand plume' stage, which means that when you shake the skimmer, dipped in this sugar, large, abundant flakes resembling feather beards detach from it. Pour in the currant juice, bring it to a boil two or three times, and the syrup is ready. Cherry syrup is made in the same way, except that there is no need to let the juice ferment, and you use exactly one pound of juice for every two pounds of sugar. These syrups, as well as all other acidic syrups, must be prepared in a silver pan or basin."
Note on the Original Text
This recipe is written in an almost poetic, imperative style, with the expectation that the reader understands basic kitchen practices and can judge doneness by appearance and feel, rather than precise temperature or time. Abbreviations and weights reflect the old French pound (livre) as a measure—slightly heavier than today’s pound, roughly 489 g. Descriptions like 'grande plume' (literally 'large feather') refer to the traditional sugar boiling point, where syrup forms long, feathery threads when tested. Spelling and word choice reflect early 19th-century French; some terms (like 'chausse de drap', a cloth filter) may be unfamiliar in modern kitchens but are evocative of the tactile intimacy of pre-industrial cookery.

This recipe hails from early 19th-century Paris, documented in 'Le pâtissier national et universel' (1836), a comprehensive manual aimed at both professionals and aspiring confectioners. At this time, fruit syrups were prized in pastry shops and aristocratic households alike—used to flavor drinks, glacés, and elaborate desserts. Preserving the intense tartness of red currants captured France's love of sharp, vibrant fruit flavors, and the care with which syrups were made reflects both advances in sugar refining and a continuing reliance on labor-intensive kitchen craft. The chef behind this recipe, Belon, was pastry chef to a cardinal, and the book itself gathers the expertise of renowned French and international pâtissiers. It bridges older manual methods and contemporary invention, revealing shifts in taste and technology amidst a bustling gastronomic capital.

Historically, a marble mortar and pestle were used to gently bruise the currants. The pulp was strained through a fine cloth sieve, then pressed in a hand-cranked fruit press. The juice rested in a stoneware (grès) bowl for fermentation, and was then filtered through a woolen 'chaussette' filter bag. Cooking took place over a wood or charcoal fire in wide, shallow pans or, as recommended, an elegant silver or copper preserving pan, prized for their heat control and non-reactive qualities. Weighing was done with balance scales, and the sugar’s readiness was tested with visual and tactile cues (the 'grande plume' or feather stage), often using a slotted spoon.

Ingredients
- Red currant juice – 2.3 lbs (from about 4.4 lbs fresh red currants)
- Granulated sugar – 4.2 lbs
- Water – as needed (for sugar clarification; optional)
- Optional substitute: use frozen red currants if fresh are unavailable
Instructions
- To make Sirop de groseilles (Red Currant Syrup) today, start by selecting approximately 2.3 lbs of fresh red currants.
- Remove the stems and gently crush the berries with a potato masher or food processor.
- Transfer the pulp into a fine sieve or cheesecloth set over a bowl, and let it drain, then press to extract as much juice as possible.
- Pour the juice into a non-reactive ceramic or glass bowl, cover lightly, and let it sit at room temperature for about 12–24 hours until slight fermentation begins (bubbles may appear and the aroma will change).
- If you prefer to skip fermentation for a fresher taste, proceed directly to the next step.
- Once the juice has started to ferment, strain it through a fine cloth.
- Measure the juice and weigh out double its weight of granulated sugar (for 2.3 lbs juice, use about 4.2 lbs sugar).
- In a large saucepan, heat the sugar with a little water, simmering until it reaches the 'feather' or thread stage (about 230°F), where the syrup thickens and forms long threads or flakes when lifted with a spoon.
- Pour in the currant juice, bring just to a boil, and let it bubble a couple of times.
- Remove from heat, cool slightly, and decant into sterilized bottles.
- Store refrigerated.
