Puzzle of the Day

I'm thinking of a letter that, although otherwise common in English, rarely appears at the end of a word; there is only one such instance in some lists of the 1000 most frequently used words. Among words that do end with this letter, an inordinate number (around 10 to 20 percent) are foods.

1. What's the letter?
2. How many of those foods can you think of?
3. Are you hungry yet?
4. BONUS: Why are so many of the words ending with this letter foods? (Coincidence? I think not.)

By the way, three Proofniks have first names ending with this letter.

Previous puzzle:

            

The set above has 5 members. What's that you say? You see 6 pictures? Well, then, tell me which two represent the same member of the set!

Answer:

Those are a thumb drive, a pointer (dog breed), a ring, a middle seat, an index, and Pinky from Pinky and the Brain. They're all fingers... and two of them are the same finger: your pointer finger is your index finger.

Whew, hard puzzle, eh? Congrats to solvers ☞ Maddy, ☞ Jason, and ☞ Mr. Gregg!
