Rhubarb season has arrived, bringing with it one of the most comforting flavors of early summer. With its unmistakable sweet-and-tart character, rhubarb transforms into a rich homemade jam that tastes just as wonderful spread over warm buttered bread as it does stirred into porridge or folded into fresh pastries.
Beyond its vibrant flavor, rhubarb is also rich in antioxidants and contains important vitamins and minerals that support the body, making it a favorite ingredient for many seasonal recipes.
Ingredients
1 kg rhubarb stalks, trimmed
750 g sugar
Juice of ½ lemon
1 vanilla bean
Preparation
To prepare the jam, you’ll need a large thick-bottomed pot, ideally stainless steel, along with a vegetable peeler, knife, and wooden spoon.
Start by thoroughly rinsing the rhubarb stalks and drying them with paper towels. Peel away the outer layer carefully using a vegetable peeler, as the fibrous skin can prevent the rhubarb from softening properly during cooking. Once peeled, chop the stalks into small pieces.
Place the rhubarb in the pot, add the sugar, and mix well. Cover the pot and allow the mixture to rest for at least 30 minutes, stirring occasionally so the rhubarb can release its juices and form a syrup.
Cook the mixture over medium heat until foam begins to rise to the surface. Skim off the foam with a strainer, then reduce the heat and let the jam simmer gently. Continue cooking until the syrup thickens and the rhubarb begins to break down into a soft texture.
Remove the pot from the heat and, after about five minutes, stir in the vanilla and lemon juice. Even though rhubarb already has a naturally tart flavor, the lemon juice plays an important role in helping preserve the jam.
While the jam cooks, prepare the jars. Wash the jars and lids thoroughly with hot water and dish soap, then rinse them well. Place them in a large pot filled with water and boil for 10 minutes once the water reaches a boil. Carefully remove the jars and allow them to dry upside down on a clean kitchen towel.
Pour the hot jam into the sterilized jars, seal them tightly, and cover them with a thick blanket to cool slowly.
