Mulberry Jam

Last Updated on June 22, 2026 by Lisa Keys

Mulberries are naturally sweet and fruity. They make a delicious jam when balanced out with fresh lemon. This homemade mulberry jam recipe is extra flavorful as it is made with less sugar. Low sugar jam really lets the fruit flavor shine.

Father's Day Inspiration

It's Father's Day and I can't help but wonder what life would be like if William had become a dad. Watching my daughter be a mother has been one of the greatest joys of my life. So, imagining him as a dad…I feel so robbed, but also just grateful for the time I did get. All these years later, I am torn.

These feelings are often difficult to navigate. I explain much about that in my Tedx talk on surviving loss, but for today, I'm going to have to jam it out. However, before I get to the mulberry jam recipe...

I suppose I am thinking a lot about William as a dad because we just had the best visit from one of his Navy brothers. Tim, a corpsman, his lovely wife and 5 children (all under the age of eleven) come to support and catch up. It gives me a glimpse of a man, much like William, being a dad.

Tim is a devoted brother and father. My heart feels full as Tim tends to the needs of his family. From assuring their safety around the pool to reminding them of good manners, he calmly guides them through the day. With love, discipline and respect the children respond in turn. Not only are they listening to their dad, but also mimicking what he does by taking care of each other.

We play, we laugh, we share a meal and all the while I feel so grateful for men like Tim in my life. Men who are filled with honor, courage and commitment to their family, friends and country.

Military Coins

Later, I discover that Tim has placed a military challenge coin on William's American flag of honor. The coin is a symbol of lasting and close-knit bonds between people who give and receive them. It's a long-standing military tradition to exchange coins representing unity.

When I ask Tim about the coin, he tells me that William did not get the chance to receive his Operation Enduring Freedom coin. However, for some reason he had two. He says, "One is meant for William". It is an emotional moment.

Jam Time: Spring Foraging

So, now, I am meant to jam it out. I need to work through my emotions, so I head outside to forage for mulberries. Did you know they grow on a tree and not on a bush? The children's song about going around the mulberry bush has it all wrong.

What are Mulberries?

And while they may look a lot like blackberries they are not related. Mulberries are sweet and rich in antioxidants. The seeds are tiny and insignificant. Mulberries are delicious in baked goods like pies and muffins, but I love them in mulberry jam with lemon and thyme. They have such a deep, rich and fruity flavor.

How to make homemade mulberry jam

There are lots of ways to make jam, but I always like mine with a touch of herbs and citrus. I add lemon thyme because I have a ton of it growing in my front yard. It's a gorgeous perennial plus has so many culinary uses. I also eliminate half the sugar in a standard jam recipe by using a low-sugar pectin.

Low-Sugar Jam Advantages

• Richer berry flavor
• Less calories per serving
• softer set jam

I use pomona universal pectin as it allows for less sugar in the recipe. Less sugar means more mulberry flavor as does the use of a bit of salt. Salt is the universal flavor enhancer, so don't leave it out. Sure-Jell also makes a low-sugar pectin. Both brands work well just follow instructions on the box.

What to eat with Mulberry Jam

• pancakes
• toast
• French toast
• biscuits
• peanut butter sandwich
• Also delicious in baked goods that call for jam

If you have grief feelings to work out I certainly recommend getting out in nature. Forage for berries and jam it out or head to a farm to pick your own berries or peaches.

Pomona Universal Pectin is a citrus pectin that requires less sugar, so the berry flavor really comes through.
