Raspberry Jelly

This is the way Grandma made raspberry jelly before grocery store pectin existed. Apples are the secret ingredient: their natural pectin sets the jelly without any added thickener, and the apple flavor stays subtle enough that the raspberry takes the spotlight.

The two-stage juice extraction is the work-intensive part. Raspberries and apples each get simmered separately with water until soft, then strained through a jelly bag (or several layers of cheesecloth) overnight for clear juice. Don’t squeeze the bag or you’ll get cloudy jelly.

Combine the juices in equal proportions and measure carefully. The two-thirds cup sugar per cup of juice ratio is what gives you the right set without a syrupy or rock-hard final product.

The “sheet test” tells you when the jelly is done. Dip a cold metal spoon into the boiling jelly, hold it sideways, and watch the drips. When two drips join and “sheet” off the edge in one drape (not separate drops), the jelly is set.

Chef Tips

• Use slightly underripe apples for the highest natural pectin content; fully ripe apples have less pectin and may not set up properly
• A candy thermometer is a backup for the sheet test; 220°F (104°C) is gel stage for most jellies at sea level
• Don’t double the recipe; small batches set better than large ones because bigger volumes don’t reduce evenly
• Sterilize jars and lids in boiling water for shelf-stable storage; refrigerate any jar that doesn’t seal properly after cooling

Variations

• Substitute crab apples or quince for regular apples for even more natural pectin and a slightly different flavor
• Use blackberries, blackcurrants, or red currants in place of (or alongside) the raspberries
• Add a teaspoon of fresh lemon juice per cup of juice for brighter flavor and extra set insurance
