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.

“This was pretty crazy. I only stumbled on this site by luck, trying to find Alum. I figured it'd be easy since it used to be in all the cupboards from Tom & Jerry cartoons, but no one has ever heard of it. That aside, I'm impressed by the product line. I got my order in ONE DAY and I love the little cartoon nuts on the box arguing over which side to open first. This is a really great operation.”

“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"”
