Let the Fruit Shine!

A clear glass mason jar of traditional Amish jam thickened with corn flour, resting on a warm wooden tabletop alongside a vintage spoon in a natural light kitchen.

Corn flour jam is an old-fashioned Amish jam recipe that creates a smooth, soft fruit spread without relying on commercial pectin. Unlike traditional homemade jams that depend on large amounts of sugar to gel, this recipe thickens with corn flour (cornstarch for our "English" readers), allowing the natural flavor of the fruit to shine. It spreads easily, even when cold, and works with almost any fresh or frozen fruit.

On our farm, we grow waxy maize and grind it into corn flour for making jams and other recipes. Most readers won't have access to waxy maize, so the closest commercial product is Clear Jel®, a modified waxy cornstarch commonly sold for home canning. It provides the same smooth, glossy texture we've relied on in Amish kitchens for generations.

If you're looking for a no-pectin jam recipe, a lower-sugar homemade fruit spread, or a traditional Amish way to preserve fruit, this family recipe lets the fruit—not the sugar—be the star.


Ingredients

  • 7 quarts/28 cups of Fruit (chopped or mashed; use food processor if you have one)
  • 2 - 3 cups Sugar (sweeten to your taste)
  • 1 cup Lemon/Lime Juice (depends on the fruit, makes most taste better)
  • 1 ⅓ cup Corn Flour (This cornstarch, not corn meal) For best results, use a waxy-maize-based cornstarch such as Clear Jel®.
  • 1 ⅓ cup Cold Water
  • Yield: 7 quarts (14 pints, 28 half-pints, or 56 quarter-pints)


Instructions

Put the fruit, sugar, and lemon juice in a pot over medium-high heat. Bring it to a boil and let it cook for about 10–15 minutes until the fruit is soft and has released its juices. You may need to add a small amount of additional water, depending on the fruit. Lower the heat to a simmer and reduce the mix until it coats your spoon without running.

In a bowl, mix the corn flour and cold water until it looks like smooth milk.

Bring the mix back up to a boil and slowly pour in the corn flour mixture. Let the jam boil for one full minute while stirring. Lower the heat and simmer for up to 5 minutes. You will see the jam turn glossy and thick. Remove from heat. Pour into clean jars, wipe rims, add flats with rings.

Canning

Water bath (WB) or Steam bath (SB) 25 min plus altitude adjustment

📌 Modern water bath recommendations for jams are often 5–10 minutes depending on altitude, acidity, and recipe style. Many modern recipes rely on higher acid levels and large amounts of sugar or commercial pectin for preservation. Traditional Amish and homestead kitchens commonly processed jams longer — often around 25 minutes — using older preservation methods and less pectin, lemon juice and sugar.

It's the same guide I keep in my own kitchen when preserving food throughout the year.
