Answer: TOMATO JUICE

The answer to each clue results in a spreadsheet-like coordinate. Words in parenthesis complete the clue.

1. 3-D (afoul); 2. A1 (Alan Moore); 3. G7 (Alistair); 4. A-1 (anchovies); 5. B12 (anemia); 6. K2 (ascent); 7. G4 (attack); 8. B-17 (bomb); 9. B17 (bus); 10. 5-O (detective); 11. L7 (electric); 12. D12 (Eminem); 13. V-8 (engines); 14. T-10 (epaulets); 15. C9 (even); 16. R17 (fast); 17. C-14 (figures); 18. K-12 (grades); 19. N8 (grandmama); 20. 8T (Great); 21. A4 (half); 22. F-18 (Hornet); 23. T2 (imitate); 24. T-20 (immune); 25. K-9 (Jerry Lee); 26. d20 (license); 27. X-15 (McLean); 28. 15X (men); 29. U2 (moniker); 30. M16 (NATO); 31. F7 (palette); 32. I-10 (Palm Springs); 33. 3M (Post-Its); 34. N-1 (prop); 35. R11 (repairman); 36. H-1 (route); 37. S13 (rule); 38. K-15 (skits); 39. 15P (solar); 40. M-1 (space); 41. A-9 (specific); 42. Y1 (strain); 43. Artoo [R2] (street); 44. K19 (submarine); 45. 15P (system); 46. W-2 (taxes); 47. U-17 (team); 48. X-8 (themes); 49. P3 (themselves); 50. A6 (virus); 51. W4 (x-ray).

Each clue begins with A or D, indicating across or down. Using this information, one gets this grid:

The second set of clues lead to coordinates within this grid, which provide letters.

1. A3 (c); 2. X-17 (l); 3. W20 (u); 4. Q1 (e) 5. R7 (t); 6. X-9 (h); 7. B6 (i); 8. C6 (r); 9. 16O (t); 10. 5K (e); 11. 20g (e); 12. 9v (n); 13. B-19 (s) 14. B-9 (p); 15. R-4 (r); 16. V2 (i); 17. E1 (m); 18. 2K (a); 19. U8 (r); 20. o-nine (y); 21. E20 (i); 22. "4U" (n); 23. K12 (g); 24. 4X (r); 25. 7i (e); 26. O5 (d); 27. V2 (i); 28. X10 (e); 29. 2A (n); 30. 4-H (t).

Taking the letters at these coordinates gives CLUE THIRTEEN'S PRIMARY INGREDIENT. Clue 13 yielded V-8, in which the primary ingredient is TOMATO JUICE.
