60 min plus standing time
4-5 8 oz jars
Raspberries and peaches are a classic combination. Here's a jam version: perfect for scones, biscuits, or toast.
  • 1 pound or 500 g peaches
  • 1 pound or 500 g raspberries
  • scant 3 cups (600 g) granulated sugar
  • juice of 1 lemon (about 3 Tbsp or 45 ml)
  • 1/4 teaspoon unsalted butter (optional)

prep the fruit

Pit the peaches but don’t bother peeling them. Chop them into bits approximately the size of the raspberries. Put both the peaches and the raspberries in a non-reactive pot (I use this 4-qt one) with the lemon juice and sugar. Combine gently, and let stand, covered, at least two hours, or as long as overnight.

meanwhile prepare jars and other equipment

Use any pot that will hold the jars and enough water to cover them by 1-2 inches. Put empty clean jars in the pot, add water to at least an inch over the tops of the jars, and bring the water to a boil. Remove jars, and let them drain upside down on a folded towel. Don’t drain the water from the pot; you’ll use it shortly.

Wash the lids in warm water and set aside (see new procedures for jar lids!) Keep the bands handy. Have an extra small jar, or custard cup, clean and ready for any excess jam. Put a couple of small saucers in the freezer to chill so they’ll be ready for testing the jam.

add a bit of butter and cook

After the fruit macerates with the sugar and lemon juice for hours, there will be plenty of juice in the pan. Cook the jam: add a tiny pat of butter (it reduces foaming), and bring the fruit mixture to a boil, stirring occasionally. Reduce heat somewhat and simmer it  until the chunks of fruit are translucent and thoroughly cooked. Blitz the preserves with an immersion blender – this will create a smooth thick texture, and will help the jam cook faster.

cook until you can make a clean streak

Return the preserves to the heat, and continue cooking, stirring often, until it bubbles and looks quite thick. I like to test for doneness by putting a spoonful on a saucer, and chilling it in the refrigerator for 2 minutes. After that time, if I can drag my finger through the jam, and leave a clear track that doesn’t fill in again, it’s ready.  In my kitchen, this took about 10 minutes more.

When the jam is ready, remove the pot from the heat. Ladle jam into prepared jars, wipe rims, and apply lids and bands. Anything that won’t fit in your four jars can go into the clean custard cup and chill it in the fridge.

Wipe the jar rims, apply lids and bands, then process for 10 minutes in a boiling water bath. Cool jars, label, and store in a dark cool place.

  1. I made this jam a few weeks ago and just opened a jar this morning. It is gorgeous, both in color and taste. Thank you for posting!
