1) In a large frying pan melt 3 of the 5 tablespoons of the butter and add the onion, carrot, celery, rosemary, sage, bay leaf, and peppercorns. Cook over a high heat, stirring occasionally, for about 15 minutes or until the onions begin to brown. That's why we use a non-stick pan, when you reduce liquid this much, it can really make a mess of other pans. By the way, the mix of 2 parts onion, to 1 part carrot, and 1 part celery is called a mirepoix (MEER-a-pwah), and is a foundation of French cooking and is common in soups, stuffings, and, of course, sauces.

2) Add the garlic and cook for about 2 minutes. Add the tomato paste and cook for about 3 minutes until it begins to darken. Add the wine and the beef stock. Boil for 30 minutes. Pour everything through a strainer into a saucepan, and squeeze the juices through the strainer with a ladle or whatever you used to stir the veggies.

3) Boil over high heat until it is reduced to about 1 cup and keep an eye on things so it doesn't burn.
