It’s Saskatoon berry season, and there’s no better time to make a batch of homemade jam! This small-batch Saskatoon jam skips the pectin and keeps things simple with just berries, sugar, and lemon juice. It’s an easy way to hold onto that rich, wild flavor and enjoy a taste of summer all year round.

Instructions
Make It
If you’re planning to can: Get your water bath canner, jars, and lids ready before the jam starts cooking. Keep everything hot.
Toss all your ingredients into a deep, heavy pot—don’t fill it more than halfway. These berries like to foam up.
Turn the heat to medium-high and start stirring. The water is there to keep things from burning while the berries wake up and start releasing their juice.
Mash them a little, if you like a smoother jam. I usually leave mine mostly whole—it gives the jam more texture and a rustic feel.
Once the pot hits a full rolling boil, keep it boiling hard for about 15 minutes. Stir often. It’s ready when it reaches 220°F at sea level, or when it passes the freezer plate test (wrinkle = done).
Pull it off the heat, skim any foam, and ladle it into jars (leave ¼ inch headspace).
If You’re Canning
Process in a boiling water bath:
10 minutes at sea level
15 minutes if you’re above 6,000 ft
Let jars sit in the water for 5 extra minutes before removing.
Cool on a towel overnight. Check seals the next day.
Store sealed jars in a cool, dark spot for up to 18 months. Unsealed jars go in the fridge.
Notes
Don’t skip the lemon juice if you’re canning—it helps with safety and flavor.
You can drop the sugar down to 2 cups if you want a softer, less sweet jam.
Saskatoons don’t break down much, so mash them well early on if you like it smooth.
