This is one of the many recipes that Colombia presented as the outcome of a most interesting scientific research method, called "food pairing." Flavor analysis was used to discover the foods that best combine with the different varieties of coffee that the country produces. The results provide a myriad of new possibilities for combining coffee with a number of other flavors to create new and unexpected recipes.
For the beef stock:
10.5 ounces white beef bone
1 pound beef flank, cut in 1-inch pieces
2 tablespoon vegetable oil
5 cups water
1 small onion, chopped coarsely
1/4 stalk celery, chopped coarsely
1 small carrot, chopped coarse
2 tablespoons tomato puree
1/2 tablespoon salt
Cheesecloth bag, containing:
1 sprig rosemary, about 2.5 inches
1 sprig thyme, about 2.5 inches
1 bay leaf
For clarifying stock:
3 cups liquid stock, fat removed
2 egg whites, beaten lightly
For infusing stock:
2 ½ cups clear stock
1.4 ounces Colombian coffee beans, from the Santander area
5 x 6 inch sprigs fresh tarragon
For peanut paste:
3.5 ounces white peanuts (aprox. 3/4 cup if measured peeled and uncrushed)
1 tablspoon vegetable oil
For peanut and beer foam:
2/3 cup dark beer, Guinness type
2 tablespoons peanut paste
2 egg whites
¼ teaspoon finely ground Colombian coffee, Santander origin
To make the stock, roast bones at 180ºC (350ºF) for 40 minutes. Save. Add a tablespoon of vegetable oil to non-stick pan, brown meat at highest temperature. Save. Add a tablespoon of vegetable oil to non-stick pan, brown vegetables. Add tomato paste and cook until liquid evaporates. Save. In a tall pot, add bones, beef, water and salt. Bring to boil, skimming the froth, and simmer uncovered for 5 hours. Add herbs in cheesecloth bag. Add vegetables and simmer for 1 additional hour. Strain the stock through a fine sieve into a bowl.
To reduce kitchen time, a pressure cooker can be used. In this case, cook meat, bones and water, under pressure, for 1 hour after correct pressure level is reached. Let pressure cooker chill until safe to open, add herbs and vegetables and cook uncovered for 1 more hour.
To clarify stock, heat the stock, and add lightly beaten egg whites. Simmer until whites curdle. Ladle stock through cheesecloth or paper sieve. Removing fat with a fat separator before this step will help you obtain a finer stock. Fat can also be removed by letting stock chill and removing solid fat gathered on top with a ladle.
To infuse stock, heat clarified stock to boiling point. Add coffee beans and tarragon. Remove from heat and allow to infuse for 10 minutes. Strain through sieve to remove beans and herbs. Strain again through cloth or paper sieve to remove any remaining solids. Taste and add more salt if necessary. At this point you should also add salt to taste.
To make the peanut paste, add oil and peanuts to pan and roast until golden, stirring continuously. Add peanuts to food processor fitted with the metal blade. Grind until a thick paste is obtained.
To make beer and peanut foam, combine all ingredients in small bowl and mix well. Strain through fine sieve or superbag. Transfer liquid mix into small siphon and screw on top tightly. Charge siphon with gas capsule.
Presentation and serving. Heat infused stock to below boiling point. Remove from heat. Fill medium pot with water to ½ of its capacity. Place siphon in pot (water should cover about ½ to 2/3’s of siphon. Heat until water is about 50ºC (122ºF). Pour warm stock into white wine glasses, about ¾ full. Shake siphon well, turn upside down and press lever to fill rest of glass with foam. Sprinkle ground coffee over foam and serve.
