Medley Hills Farm Alum Granulated Powder 3.5 lb — Food-Grade Pickling Alum for Crisp, Firm Pickles

Medley Hills Farm Alum Granulated Powder is a food-grade alum sold in a 3.5 lb resealable bag for use in traditional pickling to firm and crisp vegetables.

Packaged in a sealed, resealable Ziploc bag, this 3.5-pound container of food-grade alum (potassium aluminum sulfate) is made in the USA and intended for culinary and household uses such as classic pickle recipes. When used as directed in old-fashioned brine recipes, alum can help maintain a firmer texture in cucumbers and other vegetables during the pickling process. Store it at room temperature and keep the bag sealed for up to one year to preserve potency and prevent moisture clumping.

How is this alum used in pickling recipes?

Alum is typically added to a sealed brine where cucumbers soak for several weeks; it helps preserve the vegetable’s crunchy mouthfeel when cucumbers are at peak freshness. It is used sparingly and mixed with water, vinegar, salt, and spices to create the pickling solution.

• Add the measured alum to your brine solution before sealing jars or crocks.
• Use only the small amounts specified in traditional recipes to avoid off-flavors.
• Siply combine with vinegar, salt, water, and pickling spices for sealed-soak methods.
• Pickle vegetables at their freshest for best crispness results.

What safety and storage steps should I follow?

This product is labeled food grade and comes in a resealable bag to limit moisture exposure and contamination. Store at room temperature, keep the bag closed, and use within one year for optimal quality; follow recipe guidance for safe culinary use.

• Keep sealed when not in use to prevent clumping and moisture entry.
• Store away from heat and direct sunlight in a cool, dry cupboard.
• Use measuring tools and avoid direct hand contact with the powder.
• Follow each recipe’s recommended alum amounts and food-safety guidelines.

Will alum change flavor or appearance of my pickles?

When used correctly and in small quantities, alum primarily affects texture rather than flavor, helping vegetables remain crisp without noticeably altering taste. Overuse can impart a metallic or astringent note, so adherence to recipe quantities and short ingredient lists is important.

• Correct amounts firm texture without significant flavor changes.
• Excessive alum may introduce a slight metallic aftertaste.
• Combine with traditional salt, vinegar, and spices for familiar pickle profiles.
• Test small batches first if trying alum for the first time.
