Alum powder is a crystalline powder that is most commonly used in pickling; it keeps pickles firm and crispy.

Alum powder is often used to firm and crispen pickles by letting them soak in a sealed brine solution of water, vinegar, salt, spices, and alum powder for several weeks. Cucumbers should be pickled at the peak of freshness because they will become soft after a few days. Use up to 1/4 teaspoon of alum per pint of solution.

Alum's tissue-shrinking properties gave it a starring role in multiple episodes of the cartoon Looney Tunes in which alum was shown to comically shrink the characters' heads and pucker up lips.

“Thank you so much! The real reason for my order was for alum so my dad could tan an animal hide. While exploring your website, I saw all the wonderful treats you have, and also ended up ordering chocolate covered orange peal for my mom and Finnish licorice for my dad. They arrived today (your shipping is very fast), and Mom and Dad loved their unexpected treats, saying they both taste fantastic!!! I'll definitely be ordering from you again!”

“I'm very pleased with your low prices and extremely fast delivery! ”

, Savannah, Georgia January 8, 2011

“ Yes the package did arrive. Now I need to scrape the hide(fleshing out) and get the solution of salt water and alum to soak the hide(a tanning process). The alum helps the hair stay on the hide- which is technically called a pelt. Your company was the first one I found that I could purchase the quantity I needed. Thanks.”
