Syrup

Syrup is a concentrated liquid made by dissolving sugar or another sweetener in water, juice or another liquid. In professional kitchens, syrups are used for poaching fruit, soaking cakes, sweetening beverages, making sorbets, preserving fruit and preparing confectionery. Their concentration and texture depend on the sugar-to-liquid ratio and cooking method.

Common syrup types

• Simple syrup: sugar dissolved in water, often prepared at a 1:1 ratio by weight for beverages and general kitchen use.
• Rich syrup: a more concentrated syrup, commonly made with two parts sugar to one part water by weight.
• Flavoured syrup: infused with herbs, spices, citrus, fruit or other aromatics.
• Poaching syrup: a sweetened liquid used to cook fruit gently.
• Soaking syrup: brushed or poured over cakes such as génoise to add moisture and flavour.

Concentration and sugar stages

As syrup is boiled, water evaporates and the sugar concentration increases. In confectionery, temperature is used to identify stages such as thread, soft ball, firm ball, hard ball, soft crack and hard crack. The exact temperature ranges depend on altitude and conditions; use a reliable thermometer and a tested recipe.

Example: use a light syrup to poach pears, a flavoured syrup to soak sponge cake or a concentrated syrup as the base for selected confectionery.

Syrup versus sauce

Syrup is generally a sweetened liquid with a defined concentration. Sauce may contain additional ingredients and can be savoury or sweet, with a wider range of textures.

Chef’s tip: specify ratios by weight for consistency, and cool and store syrups using appropriate food-safety procedures. Flavoured syrups may have different shelf lives depending on ingredients and handling.
