Ingredients
Here’s what you’ll need to make this delicious keto strawberry rhubarb jam:
- 2 cups fresh strawberries, hulled and chopped
- 2 cups fresh rhubarb, diced
- 1/4 cup water
- 1/4 cup powdered erythritol or monk fruit sweetener
- 1 tbsp lemon juice
- 1 tsp pure vanilla powder
- 1/2 tsp xanthan gum (optional, for thickening)

Instructions
Step 1: Prepare the Fruit
Wash and chop the strawberries and rhubarb into small pieces. The smaller the pieces, the quicker they’ll break down.
Step 2: Cook the Jam
In a medium saucepan, combine the strawberries, rhubarb, water, and sweetener. Bring to a simmer over medium heat, stirring occasionally.
Step 3: Thicken the Jam
Once the fruit has softened (about 10-15 minutes), mash it with a fork or potato masher to your desired consistency. Stir in lemon juice and vanilla powder. For a thicker jam, sprinkle xanthan gum while stirring continuously.
Step 4: Cool and Store
Remove from heat and let cool. The jam will thicken further as it cools. Transfer to a clean jar and refrigerate for up to 2 weeks.
