Ingredients

Rhubarb is available before strawberries are. Gather and freeze the rhubarb until the garden strawberries have ripen.

  • 2 pounds fresh rhubarb stalk, cut into 1-inch pieces
  • 2 pounds fresh strawberries, remove the green tops and cut berries in half
  • granulated sugar, 1 cup
  • light brown sugar, 1 cup
  • vanilla extract, 1 tablespoon

Equipment

Preparing this recipe over the stove is doable. Simply set the over burner to low and allow the ingredients to simmer for 45 minutes(ish). Take note to use non-reactive pots such as stainless steel, enamel dutch oven, or a copper jam pot.

Because we are busy, the use of an electric slow cooker is practical and much more convenient.

  • 8-quart slow cooker
  • silicon spatula
  • steam canner, or hot water bath canner
  • immersion blender (stick blender)
  • jar funnel
  • air bubble remover
  • 1/2-pint mason jars, or pint-size jars

Slow Cooking Instructions

This is a prepare and walk away recipe. Go about tending to the family, garden, or livestock and allow the ingredients to transform themselves into a delicious and easy rhubarb strawberry butter.

  1. Add all the ingredients to the slow cooker, gently folding the ingredients until thoroughly mixed.
  2. Place lid onto the slow cooker at an angle, do not latch the lid.
  3. Place the setting to low and set the timer to 4 hours.
  4. Stir the mixture often to ensure the sugars are mixed with the strawberries and rhubarb.
  5. Once the rhubarb has completely softened, the strawberry rhubarb butter is done.
  6. Using an immersion blender, slowly blend the rhubarb butter, taking care to not over blend. If the butter appears to be watery, slow cook the butter on high with the lid off until the desired consistency has been met.

Canning Instructions

Processed the pint jars using either a steam or hot water bath canner.

A steam canner is a much more efficient tool which uses 2 inches of water and processes jars with steam. Unlike the steam canner the hot water bath canner processes jars using boiling water.

  2. Remove any air bubbles using the air bubble remover. Add additional strawberry rhubarb butter as needed.
  3. With a clean dishtowel, wipe the rims of the jars. Add warmed lids and rings finger tight.
  4. Process the strawberry rhubarb butter in a steam or hot water bath canner based on your altitude, see notes.

    Thank you for this post. My rhubarb is ready and I am so busy. Off to the store to buy the berries. Love your site

  2. Michelle bracht says

    Thanks for the recipe! After several years I finally got rhubarb to grow in Oklahoma. No strawberries this year though. Will this recipe be ok with just rhubarb? I really try to only use what I grow.
    Thanks!
    Michelle

    • Farm Girl says

      Rhubarb is tart, but the sugars sweeten it. The strawberries only balance it out more. If you are looking for items to add to the rhubarb, pineapple works great too!

    • Martha says

      There is a recipe for rhubarb sauce over at the Old Farmer’s Almanac that you might want to try. It’s made with all rhubarb (sugar and water are the only other ingredients).

  3. Kelsea says

    I have frozen rhubarb that I put away earlier this spring. Will that work? Do I let it thaw or put it in frozen?

  4. Marissa says

    5 stars
    Can you freeze the strawberry rhubarb butter after you make it? Also, do you need to use pectin? I don’t see it listed.

    Thanks!

    • Ann Accetta-Scott says

      Hi there, it can be frozen instead of canned. Because it is a butter and not a jam or jelly, pectin is not needed. It is meant to spread like butter.
