Red Wine Reduction2017-12-21
Saute onion, celery, carrots, and garlic in oil in a 6-quart heavy pot over moderately high heat, stirring, until golden, about 10 minutes. Add wines and simmer, stirring occasionally, until mixture is reduced to 1 quart, about 1 hour. Pour through a sieve into a saucepan and simmer until reduced to 2 cups. Reheat reduction and season with salt and pepper before using.
