Gland for Some Home Cooking

 is an unmarked quest in Fallout: New Vegas.

Detailed walkthrough
This quest is given by Ruby Nash. She is a kindly old sort, and if you ask her what she cooks, she lets you know all about her Radscorpion Venom Casserole.

Tell her you’re keen on trying some of it, and she asks how many Radscorpion poison glands you have. Assuming the answer is “none,” she urges you to go out and find some.

Return with the glands, and you’re given Ruby’s casseroles (in increments of five, based on the number of glands you recover).

Ruby’s Casserole has also attracted the attention of Corporal William Farber over at Camp McCarran, who may be interested in sampling some as part of Free Quest: Not Worth a Hill of Corn and Beans. Unfortunately, Farber isn’t interested in such small quantities.
