Aromatic solubility describes how readily aroma and flavour compounds dissolve in different liquids or fats. Some compounds are more soluble in water, others in fat or alcohol. Choosing the right cooking medium can influence how aromas are extracted, carried through a dish and perceived during eating.
Water-based liquids extract many water-soluble compounds, while fats can dissolve and carry many fat-soluble aroma compounds. Alcohol can also dissolve certain aromatic substances that are less soluble in water. The result depends on the compound, concentration, temperature, time and composition of the food.
Solubility describes how a compound dissolves in a particular medium. Extraction is the process of transferring compounds from an ingredient into that medium. Solubility influences extraction, but temperature, time, surface area and agitation also matter.
Chef’s tip: Match the medium to the ingredient and the desired result. Infusing herbs in oil, steeping tea in water and adding wine to a pan sauce are different ways of extracting different flavour components.
Key distinction: Aromatic solubility explains why flavour compounds behave differently in water, fat and alcohol; it is not the same as the strength or intensity of an ingredient’s aroma.
