Indulge in the vibrant tastes of summer with our irresistible homemade Blackberry Jam straight from the heart of our dining hall kitchen.

Whether spread generously on warm toast or lavishly layered in your favorite desserts, this jam promises a summer celebration of flavor that captures the essence of sunny days and lazy afternoons. Watch Chef Vivian make it in the new episode of Cooking With The Seasons.


8 cups of fresh blackberries

1 cup of brown sugar

The juice of ½ to 1 lemon

Optional: cardamom & allspice


  1. In a saucepan, cook blackberries and sugar over medium heat until the blackberries begin to break down, about 10-15 minutes.
  2. Reduce heat and simmer on low for about 15 minutes, until the berries start to thicken. Then, add the lemon juice and spices (if desired).
  3. Check for consistency. We want a jam that is thick but spreadable.
  4. When the juice is reduced, remove the spices, and using a potato masher, mash the berries until the berries are mostly broken down but you can still see some fruit.
  5. Let sit for 10 minutes. You can save this in an airtight container in your fridge for at least 7-10 days.
  6. Enjoy with a slice of toast, baked goods, by itself, or with anything else.

For a savory twist and endless culinary possibilities, transform this jam into a delectable sauce that is perfect for salmon by adding your favorite chili and onions. Add jalapeño for a moderate heat level and bright flavor. Bring in one of our favorites, chipotle, for a smoky, earthy flavor with moderate to high heat. Serrano chilies impart a rich, complex taste with a hint of sweetness, making them a popular choice for adding depth to sauces, marinades, and other dishes. Watch the heat on this one; serrano peppers are hotter than jalapeños, offering a more intense spiciness. They also have a slightly fruitier and more vibrant flavor, which can add depth and complexity to dishes.
