Cook all of your ingredients in a pot on the stove on medium low or about 15 minutes.
While it's cooking, mash the berries. If you don't have a masher, use a fork.
If you are making pancakes or waffles, make sure that you start it at the very beginning so that it’s done by the time your other food is done.
Notes
Go slow with adding lemon. Start with less than you think you want and taste test it. Add more if you choose to. You can never get the flavor back out of something, but you can always add more.
You can use fresh fruit, I use frozen before of where I live and convenience.
