Mincing breaks down plant cell walls, leading to a greater release of volatile oils and aromatic compounds compared to larger cuts. This intensifies the flavor and aroma of the minced ingredient.
Mincing involves finely chopping an ingredient into very small pieces. This process physically disrupts the cellular structure of the plant or ingredient. Plant cells contain oils and aromatic compounds within their cell walls. When you mince, you rupture these cell walls, allowing these compounds to escape more readily. The increased surface area created by mincing also contributes to a faster rate of evaporation of these volatile compounds, further enhancing the aroma. Think about mincing garlic versus using a whole clove – the minced garlic has a much stronger and more immediate aroma. The same principle applies to herbs, spices, and other aromatic ingredients. The finer the mince, the greater the release of oils and aromas.
To prevent bitterness when mincing garlic, avoid over-mincing or crushing it into a paste. Over-processing can release excessive amounts of allicin, a compound that contributes to a pungent and sometimes bitter flavor. A gentle mince is usually sufficient.
