Blackberry jam is a sweet, fruity spread made by cooking ripe blackberries with sugar (and sometimes a splash of lemon juice) until the mixture thickens into a glossy, rich preserve. It has a deep, dark purple color and a bold, tangy-sweet flavor that captures the essence of fresh blackberries at their peak.
 
Blackberry jam is perfect on toast, biscuits, scones, yogurt, or as a filling for baked goods like thumbprint cookies or cakes. Its vibrant taste also pairs beautifully with creamy cheeses and savory dishes.
