Rhubarb Season and Selection Tips
Choosing the right rhubarb is the first step to a standout strawberry rhubarb jam. Look for crisp, firm stalks with vivid color and no limpness or brown spots.
Young rhubarb tends to be more tender and less fibrous, while mature stalks may require longer cooking to soften. Proper selection reduces added sweetness and preserves a fresh, tangy character.
How to Prep Rhubarb for Jam
Trim the rhubarb by cutting off the leafy tops and the base, then peel the outer strings if the skin feels tough. Chop the stalks into even pieces so they cook quickly and release their flavor.
For a smoother texture, you can puree some cooked rhubarb and return it to the pot, leaving some chunks for a rustic bite.
Strawberry Prep and Layering Flavors
Hull and dice the strawberries so they integrate easily with the rhubarb without releasing excess liquid too soon. For deeper flavor, macerate the strawberries with a spoonful of sugar for 15 minutes before cooking.
Add warm spices like cinnamon or a splash of orange zest to create subtle complexity while still letting the rhubarb strawberry jam remain the star.
Cooking and Setting Rhubarb Strawberry Jam
Simmer the rhubarb first to soften it, then add the strawberries and sugar and cook until the mixture thickens. A small amount of lemon juice helps the natural pectin activate and creates a clean set.
Test the set by chilling a spoonful on a plate; when it wrinkles as you push it with your finger, the jam is ready. Avoid overcooking, which dulls the color and fresh flavor.
