This sauce works great with fresh berries as well as frozen. We get gallons of blackberries off our bushes each year.


We use a bunch during the summer and freeze the rest for sweet treats during the year. I used some frozen berries to make the sauce for Donna’s cheesecake and fresh berries when I made it for the blackberry shortcake cake.

Can this recipe be frozen for late4r use
You can. The consistency may be a bit different when you thaw it. If it is, just warm it back up in a saucepan and it should be good as new.
Good sauce, easy directions!
I am so happy that you liked it!
So easy! I added a capful of vanilla right at the end of cooking, that balanced out the tartness of the lemon and some of our berries, without getting too sweet. I’ll make a bigger batch next time and try canning them. Thanks!
Vanilla sounds like a great addition!
Absolutely delicious! Do you know how long this recipe can keep in the freezer?
I’m glad you like it! It will be good in the freezer for several months.
I was cleaning and freezing my blackberries and used this sauce recipe for the not so perfect ones. It was both easy and delicious. I thickened it and put it in canning jar in the fridge. We will enjoy it over pancakes and ice cream. Thank you for sharing.
Such a great use for the B quality berries! I am so glad you liked it.
I make a similar treet with blueberries to serve over lemon pound cake.
I make a blueberry version sometimes too! It is so good with lemon treats, or on pancakes!
A question. How long can it keep in the fridge?
A week or two. Any longer than that, and I would stick it in the freezer. It will be a little thinner when defrosted, but it will still taste good.
Can this sauce be frozen?
You can freeze it. However, if you used the cornstarch to thicken it, the defrosted sauce will be thinner than it was when you put it in the freezer.
