Ingredients

1 jar (10 to 12 ounces) seedless raspberry jam (about 1 cup) 

1 package (10 ounces) frozen strawberries 

Preparation

In a medium saucepan, heat raspberry jam over medium heat, stirring occasionally, until liquefied, about 3 minutes.

Add frozen strawberries. Simmer until softened, 5 to 10 minutes. With a potato masher, lightly mash strawberries, leaving some large pieces. Cool completely.

Transfer to an airtight container; refrigerate up to 1 week. (If sauce solidifies, warm in the microwave or over low heat.)
