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.

“Once again you have come through in the nick of time My order came the NEXT day. WOW!. Your products are WONDERFUL! Thank you for being a business that lives up to your word.”

“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.”
