Alum is an acidic powder that acts as a preservative.

Use it to make pickles or to keep fruits and vegetables crisp and fresh.

It can also go into baking recipes, to aid in leavening.

Some chefs might know Alum Powder by its other names: aluminum potassium sulfate or potash alum.

    Culinary Alum

    I bought alum elsewhere online which turned out not to be culinary, so I’m thankful to finally find the right stuff at such a low price. Consistency is more like granules than powder (which is evident in the pictures).
