Blubarb Jam

7 C. rhubarb, chopped

4 1/4 C. blueberries

4 1/4 C. sugar

1/3 C. lemon juice


The night before you want to make the jam or the morning of. Add the rhubarb, blueberries, sugar and lemon juice to a large pot, stir to combine. Let macerate for 30 min. to overnight. Sterilize jars and lids. Place a small plate in the freezer.  When ready to make the jam place the pot with the fruit in it on the stove. Bring to a boil on medium-high heat and boil hard for 15-25 minutes or until you reached the setting point, stirring occasionally. At the setting point, the foam will have subsided and the bubbles will get larger looking like fish eyeballs.  Place a small amount of the jam (1 tsp.) on the freezer plate and place the plate back in the freezer for a few minutes to cool. If the jam seems very close then remove the pot from the heat while the plate is in the freezer. If the jam wrinkles when pushed with your finger the jam is done. If not return to a boil for 5 min. and repeat. Careful as the jam thickens it can start to burn so stir more frequently.  Ladle jam into hot jars to within 1/4″ of the top. Remove air bubbles and wipe the rim with a clean cloth. Place lids on and screw to tighten until finger-tip tight only. Place in a water bath canner and process for 10 min. or according to altitude.  When the jam has cooked for its allotted time removed the jars to a towel-lined counter to cool. You should hear the popping of the lids as they seal. That is a very satisfying sound. If any jars don’t seal refrigerate and eat right away.


Pectin Version


4 ½ C. rhubarb, chopped

2 1/2 C. fresh blueberries

3/4 C. water

1 T. lemon juice

4 1/2 C. of sugar

1 box of low-sugar or no-sugar pectin

8 jam jars for canning (8 oz size)

8 canning lids


Sterilize your canning jars, and canning lids. Drain on clean dishtowels and set aside. Fill canning pot with water and bring to a gentle boil— keep over heat throughout prep so it is ready when needed. Wash berries. Measure out blueberries in a bowl. Mush them so they get quite juicy but there are still chunks remaining (mushing releases the pectin needed to make jam). In a separate bowl, mix 1 box of pectin with U C. of the sugar. Measure out remaining sugar in another bowl. Boil rhubarb and water over high heat, cover and simmer for 5 minutes over medium heat. Add the mushed blueberries, lemon juice, and pectin and mix together. Bring to a boil then add sugar. Stir and bring back to a vigorous boil again, while stirring continuously. Boil hard while continuing to stir for 1 minute (and 1 minute only—if you want jam that will set, this is serious, people). Remove from heat, stir and ladle hot jam into sterilized jars, securing lids tightly. Place jam jars in your canning pot with gently boiling water and boil for 5 minutes (again, keep your time on this—too long may make your jam runny). Remove jam and allow to cool. Check lid seals once cooled—any tops that pop back when pressed should be refrigerated. Makes 7-8 8oz (1 C.) jars of jam
