Late summer in farm country runs on sweet corn. Bushels come off the field, kernels get cut for the freezer and the canning jars, and the cobs pile up. Old farmhouses turned those cobs into corncob jelly, a sweet, honey-colored preserve that tastes like nothing else. Three ingredients, one Saturday afternoon, and the empty cob pile becomes a year of breakfast jam.

Makes about 5 half-pint jars.

Ingredients:

• 12 fresh sweet corn cobs, kernels removed (save kernels for another use)
• 8 cups water
• 4 cups sugar
• 1 box (1.75 oz) powdered pectin
• 1 tablespoon lemon juice (for color and acidity)

Instructions:

1. Make the corncob stock. Break each cob in half. Place in a large pot with 8 cups of water. Bring to a boil, then reduce to a simmer and cook 45 minutes, until the water has turned golden and tastes sweet.
2. Strain. Lift out the cobs (compost them). Pour the stock through a fine-mesh sieve lined with cheesecloth to catch any debris. You should have about 4 cups of corncob stock.
3. Combine with pectin. Return the strained stock to a clean pot. Stir in the powdered pectin and the lemon juice. Bring to a hard rolling boil that cannot be stirred down.
4. Add sugar. Pour in all the sugar at once, stirring to dissolve. Return to a rolling boil and cook exactly 1 minute, stirring constantly.
5. Remove from heat. Skim any foam from the top.
6. Jar it. Ladle hot jelly into sterilized half-pint jars, leaving ¼ inch of headspace. Wipe rims, seat lids, screw rings fingertip-tight.
7. Process. Water-bath process for 10 minutes.
8. Cool. Lift jars onto a towel and let sit 24 hours undisturbed. Check seals before storing in the pantry.

Honey crossed with toasted corn. The sweetness is deep and clean, with a faint roasted edge from the simmered cobs. It is not a strong, fruit-jam flavor; it is a gentle, almost butterscotch sweetness. Try it spread on warm biscuits, on a slice of fresh cornbread, glazed over ham, or with a sharp aged cheddar.

• Fresh corn only. Cobs that have sat for days lose flavor. Use within 24 hours of shucking.
• Sweet varieties work best. Silver Queen, Ambrosia, Peaches and Cream, or any standard sweet corn. Field corn cobs give a flatter, less sweet jelly.
• Do not boil too long. Boiling the cobs beyond 45 minutes can pull out tannins and turn the jelly bitter.
• Cheesecloth strain. Skip this step and you get a cloudy jelly. The clear, sparkling golden color is what makes corncob jelly look like liquid sunshine in the jar.
• Pectin matters. Powdered pectin works most reliably; liquid pectin will work but requires a different ratio.

Once you start using the whole ear, the rest of corn season opens up. Roast the kernels into corn relish, freeze whole cobs to grill in winter, dry kernels for cornmeal or popcorn. The Midwest farm kitchen wasted very little of any harvest, and the recipes survive because they work.
