Cabernet Sauvignon to minimize the perception of tannins—such as in the classic pairings of Cabernet Sauvignon with "steak au poivre" and pepper-crusted ahi tuna. Fats and proteins reduce the perception of tannins on the palate. When Cabernet Sauvignon is paired with steak or dishes with a heavy butter cream sauce, the tannins are neutralized, allowing the fruits of the wine to be more noticeable. In contrast, starches such as pastas and rice will have little effect on tannins. The bitterness of the tannins can also be counterbalanced by the use of bitter foods, such as radicchio and endive, or with cooking methods
Reduction (cooking) Reduction (cooking) In cooking, reduction is the process of thickening and intensifying the flavor of a liquid mixture such as a soup, sauce, wine, or juice by simmering or boiling. Reduction is performed by simmering or boiling a liquid such as stock, fruit or vegetable juices, wine, vinegar, or a sauce until the desired concentration is reached by evaporation. This is done without a lid, enabling the vapor to escape from the mixture. Different components of the liquid will evaporate at slightly different temperatures, and the goal of reduction is to drive away those with lowest points of evaporation. While
