Brown Turkey Stock

Directions

1. 1
   If using turkey wings, halve at joints with a cleaver or large knife, then crack wing bones in several places with back of cleaver or knife.
2. 2
   (There is no need to crack bones if using drumsticks or thighs.)
3. 3
   Heat 1/4 cup oil in an 8- to 10-quart heavy pot (see cooks' note, below) over moderate heat until hot but not smoking.
4. 4
   While oil is heating, pat turkey parts dry.
5. 5
   Cook turkey in 4 batches, turning once, until golden brown, 8 to 10 minutes per batch, transferring to a large bowl.
6. 6
   Add remaining tablespoon oil to pot, then cook onions, cut sides down first, turning once, until golden brown, about 5 minutes total, and transfer to bowl with turkey.
7. 7
   Cook celery and carrots, stirring occasionally, until golden, about 3 minutes.
8. 8
   Add browned turkey and onions and remaining ingredients to pot and bring to a boil over high heat, skimming froth as necessary.
9. 9
   Reduce heat and gently simmer, partially covered, 3 hours.
10. 10
    Remove pot from heat and cool stock to room temperature, uncovered, about 1 hour.
11. 11
    Pour stock through a large fine-mesh sieve into a large bowl and discard solids.
12. 12
    Measure stock: If there is more than 10 cups, boil in cleaned pot until reduced; if there is less, add water.
13. 13
    If using stock right away, let stand until fat rises to top, 1 to 2 minutes, then skim off and discard fat.
14. 14
    If not, cool stock completely, uncovered, then chill, covered, before skimming fat (it will be easier to remove when cool or cold).
15. 15
    If you are thickening your gravy with cornstarch, bring 1 cup stock to room temperature to liquefy.
16. 16
    Reheat stock before making gravy .
