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.

“Alum was impossible for me to find. I use this for a recipe for Sweet Irish Pickles...THANK YOU for carrying it! I exhaused all my avenues, including pharmacies here in Oklhaoma. NO one had Alum. I got puzzled looks and the comment= " Ihave never heard of it"”

“I ordered this for tanning leather, so this review is not regarding the taste of the product; the package arrived a day before I expected it and was well packaged in a fun box. I would certainly purchase from here again (including actual food!).”

“Great pricing and great service!”

“I am looking forward to making some delicious pickles!!! Do you know of any other way I can use this alum? Would love to hear.

Just want to let you know my package came to me in perfect shape. The only thing, which is comical to me was my husband. He thought it was something other than what it was. The "Nuts" got to him. I said "that's the name of their company." He didn't believe me at first. When I told him that it was the alum he said " what "? I loved it. Keep on being nutty!!!!
Thanks!!!! Louise”

“I ordered 3 lbs. of alum powder for tanning. had the best price I could find, and my order came so fast! I came home to find my package opened by my daughter, who was so intrigued by the messages on the box, and said she just couldn't help herself, lol! I will definitely order other items, and am telling all my friends!”
